We look at the division of 15587872 by 871 
We want to divide 15587872 by 871.

Let's proceed to step 1:
871 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 871

On to step 2:
When dividing 15 by 871, we get 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.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 871

On to step 3:
When dividing 155 by 871, we get 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Append the next digit (8) from the dividend to 155 and continue with: 1558 / 871

Moving on to step 4:
If we divide 1558 by 871, we get 1 and a remainder of 687.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 871 from 1558 leaves us with 687.
Bring next digit (7) of the dividend behind the 687 and repeat the process: 6877 / 871

Advancing to step 5:
871 goes into 6877 7 times with a remainder of 780.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 6097 from 6877 to get 780.
Fetch the next digit (8) from the dividend, attach it to 780 and continue: 7808 / 871

Moving on to step 6:
When dividing 7808 by 871, we get 8 with a remainder of 840.
Put 8 as the next digit of the answer. 
Result so far: 178.0
Deduct 6968 from 7808 and we're left with 840.
Fetch the next digit (7) from the dividend, attach it to 840 and continue: 8407 / 871

Advancing to step 7:
If we divide 8407 by 871, we get 9 and a remainder of 568.
Write down 9 as next digit of the result. 
Result so far: 1789.0
Deduct 7839 from 8407 and we're left with 568.
Append the next digit (2) from the dividend to 568 and continue with: 5682 / 871

Moving on to step 8:
871 goes into 5682 6 times with a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 17896.0
The remainder is 456 after subtracting 5226 from 5682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 9:
4560 divided by 871 is 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 17896.5
Subtract 4355 from 4560 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 10:
871 can be fit into 2050 2 times, resulting in a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 17896.52
Subtract 1742 from 2050 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
If we divide 3080 by 871, we get 3 and a remainder of 467.
Write down 3 as next digit of the result. 
Result so far: 17896.523
Subtract 2613 from 3080 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 12:
When dividing 4670 by 871, we get 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 17896.5235
If we subtract 4355 from 4670, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 13:
871 goes into 3150 3 times with a remainder of 537.
Put 3 as the next digit of the answer. 
Result so far: 17896.52353
If we take 2613 away from 3150, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Let's proceed to step 14:
When dividing 5370 by 871, we get 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 17896.523536
Subtract 5226 from 5370 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
The number 871 fits into 1440 1 times, leaving a remainder of 569.
The next digit of our result is 1. 
Result so far: 17896.5235361
Subtracting 871 from 1440 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Step 16:
If we divide 5690 by 871, we get 6 and a remainder of 464.
The next digit of our result is 6. 
Result so far: 17896.52353616
Subtract 5226 from 5690 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 17896.52353616, with a leftover of 4.64e-07.
