We're dividing 15817103 by 980 
We want to figure out the number of times 15817103 can be divided by 980.

Going ahead to step 1:
If we divide 1 by 980, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 980

Step 2:
15 divided by 980 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 980

Step 3:
980 goes into 158 0 times with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Grab the next digit (1) from the dividend, add it to 158, then carry on: 1581 / 980

Advancing to step 4:
If we divide 1581 by 980, we get 1 and a remainder of 601.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 601 after subtracting 980 from 1581.
Append the next digit (7) from the dividend to 601 and continue with: 6017 / 980

On to step 5:
The number 980 fits into 6017 6 times, leaving a remainder of 137.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 5880 from 6017 and we're left with 137.
Take the next digit (1) from the dividend and append it to 137, then repeat: 1371 / 980

Moving on to step 6:
The number 980 fits into 1371 1 times, leaving a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Deduct 980 from 1371 and we're left with 391.
Grab the next digit (0) from the dividend, add it to 391, then carry on: 3910 / 980

Going ahead to step 7:
When dividing 3910 by 980, we get 3 with a remainder of 970.
Put 3 as the next digit of the answer. 
Result so far: 1613.0
Subtracting 2940 from 3910 leaves us with 970.
Append the next digit (3) from the dividend to 970 and continue with: 9703 / 980

Moving on to step 8:
980 goes into 9703 9 times with a remainder of 883.
Write down 9 as next digit of the result. 
Result so far: 16139.0
The remainder is 883 after subtracting 8820 from 9703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Let's proceed to step 9:
8830 divided by 980 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 16139.9
The remainder is 10 after subtracting 8820 from 8830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
980 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 16139.9
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
980 can be fit into 1000 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 16139.901
Subtracting 980 from 1000 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 980 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 16139.901
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
980 goes into 2000 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 16139.90102
If we subtract 1960 from 2000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 980 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 16139.90102
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
The number 980 fits into 4000 4 times, leaving a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 16139.9010204
If we take 3920 away from 4000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
The number 980 fits into 800 0 times, leaving a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 16139.9010204
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 16139.9010204, and the remainder is 8e-07.
