Let's divide 99390490 by 980
We want to figure out the number of times 99390490 can be divided by 980.

Let's proceed to step 1:
980 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 980

Let's proceed to step 2:
99 divided by 980 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 980

Going ahead to step 3:
The number 980 fits into 993 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 980 away from 993, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 980

Moving on to step 4:
The number 980 fits into 139 0 times, leaving a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 139 after subtracting 0 from 139.
Grab the next digit (0) from the dividend, add it to 139, then carry on: 1390 / 980

Advancing to step 5:
If we divide 1390 by 980, we get 1 and a remainder of 410.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 980 from 1390 leaves us with 410.
Bring next digit (4) of the dividend behind the 410 and repeat the process: 4104 / 980

Moving on to step 6:
4104 divided by 980 is 4 with a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 1014.0
If we take 3920 away from 4104, we end up with 184.
Include the next digit (9) from the dividend after 184, then repeat: 1849 / 980

Moving on to step 7:
The number 980 fits into 1849 1 times, leaving a remainder of 869.
The next digit of our result is 1. 
Result so far: 10141.0
Deduct 980 from 1849 and we're left with 869.
Append the next digit (0) from the dividend to 869 and continue with: 8690 / 980

Moving on to step 8:
The number 980 fits into 8690 8 times, leaving a remainder of 850.
Write down 8 as next digit of the result. 
Result so far: 101418.0
Subtracting 7840 from 8690 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 9:
980 can be fit into 8500 8 times, resulting in a remainder of 660.
The number 8 becomes the next digit in our result. 
Result so far: 101418.8
Deduct 7840 from 8500 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 10:
If we divide 6600 by 980, we get 6 and a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 101418.86
Deduct 5880 from 6600 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 11:
980 can be fit into 7200 7 times, resulting in a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 101418.867
The remainder is 340 after subtracting 6860 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 12:
If we divide 3400 by 980, we get 3 and a remainder of 460.
Use 3 as the next digit of our solution. 
Result so far: 101418.8673
The remainder is 460 after subtracting 2940 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 13:
If we divide 4600 by 980, we get 4 and a remainder of 680.
Put 4 as the next digit of the answer. 
Result so far: 101418.86734
The remainder is 680 after subtracting 3920 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 14:
When dividing 6800 by 980, we get 6 with a remainder of 920.
Put 6 as the next digit of the answer. 
Result so far: 101418.867346
Subtracting 5880 from 6800 leaves us with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

On to step 15:
If we divide 9200 by 980, we get 9 and a remainder of 380.
Record the quotient 9 as the next digit in the result. 
Result so far: 101418.8673469
If we subtract 8820 from 9200, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 16:
When dividing 3800 by 980, we get 3 with a remainder of 860.
The number 3 becomes the next digit in our result. 
Result so far: 101418.86734693
Subtracting 2940 from 3800 leaves us with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

After the division, we end up with 101418.86734693 and a remainder of 8.6e-07.
