Let's divide 89123669 by 980
We want to divide 89123669 by 980.

Step 1:
8 divided by 980 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 980

On to step 2:
89 divided by 980 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 980

Moving on to step 3:
The number 980 fits into 891 0 times, leaving a remainder of 891.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 891, we end up with 891.
Fetch the next digit (2) from the dividend, attach it to 891 and continue: 8912 / 980

Going ahead to step 4:
The number 980 fits into 8912 9 times, leaving a remainder of 92.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 8820 from 8912 and we're left with 92.
Include the next digit (3) from the dividend after 92, then repeat: 923 / 980

On to step 5:
When dividing 923 by 980, we get 0 with a remainder of 923.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 923 after subtracting 0 from 923.
Grab the next digit (6) from the dividend, add it to 923, then carry on: 9236 / 980

Advancing to step 6:
980 goes into 9236 9 times with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 909.0
Subtract 8820 from 9236 to get 416.
Grab the next digit (6) from the dividend, add it to 416, then carry on: 4166 / 980

Advancing to step 7:
980 goes into 4166 4 times with a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 9094.0
Subtract 3920 from 4166 to get 246.
Grab the next digit (9) from the dividend, add it to 246, then carry on: 2469 / 980

On to step 8:
2469 divided by 980 is 2 with a remainder of 509.
The number 2 becomes the next digit in our result. 
Result so far: 90942.0
Subtract 1960 from 2469 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
When dividing 5090 by 980, we get 5 with a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 90942.5
If we take 4900 away from 5090, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
1900 divided by 980 is 1 with a remainder of 920.
Write down 1 as next digit of the result. 
Result so far: 90942.51
Subtracting 980 from 1900 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.

Let's proceed to step 11:
The number 980 fits into 9200 9 times, leaving a remainder of 380.
The next digit of our result is 9. 
Result so far: 90942.519
Deduct 8820 from 9200 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
The number 980 fits into 3800 3 times, leaving a remainder of 860.
Use 3 as the next digit of our solution. 
Result so far: 90942.5193
The remainder is 860 after subtracting 2940 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Advancing to step 13:
The number 980 fits into 8600 8 times, leaving a remainder of 760.
Use 8 as the next digit of our solution. 
Result so far: 90942.51938
The remainder is 760 after subtracting 7840 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 14:
7600 divided by 980 is 7 with a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 90942.519387
Subtracting 6860 from 7600 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 15:
980 can be fit into 7400 7 times, resulting in a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 90942.5193877
The remainder is 540 after subtracting 6860 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 90942.5193877 and a remainder of 5.4e-06.
