Let's divide 15589970 by 980
We're looking to find how many times 980 goes into 15589970.

Moving on to step 1:
When dividing 1 by 980, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 980

On to step 2:
980 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 980

Let's proceed to step 3:
If we divide 155 by 980, we get 0 and a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Include the next digit (8) from the dividend after 155, then repeat: 1558 / 980

On to step 4:
1558 divided by 980 is 1 with a remainder of 578.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 980 from 1558, we get 578.
Grab the next digit (9) from the dividend, add it to 578, then carry on: 5789 / 980

Step 5:
980 can be fit into 5789 5 times, resulting in a remainder of 889.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 4900 from 5789 and we're left with 889.
Include the next digit (9) from the dividend after 889, then repeat: 8899 / 980

Advancing to step 6:
8899 divided by 980 is 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we take 8820 away from 8899, we end up with 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 980

Moving on to step 7:
When dividing 797 by 980, we get 0 with a remainder of 797.
Put 0 as the next digit of the answer. 
Result so far: 1590.0
Subtracting 0 from 797 leaves us with 797.
Bring next digit (0) of the dividend behind the 797 and repeat the process: 7970 / 980

Going ahead to step 8:
7970 divided by 980 is 8 with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 15908.0
If we subtract 7840 from 7970, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
If we divide 1300 by 980, we get 1 and a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 15908.1
If we take 980 away from 1300, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
When dividing 3200 by 980, we get 3 with a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 15908.13
Subtract 2940 from 3200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
When dividing 2600 by 980, we get 2 with a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 15908.132
Subtracting 1960 from 2600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 12:
980 goes into 6400 6 times with a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 15908.1326
If we take 5880 away from 6400, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 13:
If we divide 5200 by 980, we get 5 and a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 15908.13265
Deduct 4900 from 5200 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
If we divide 3000 by 980, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 15908.132653
Deduct 2940 from 3000 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
980 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 15908.132653
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 16:
If we divide 6000 by 980, we get 6 and a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 15908.13265306
Subtracting 5880 from 6000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 15908.13265306 and a remainder of 1.2e-07.
