15872850 ÷ 871 
Our goal is to divide 15872850 by 871.

Moving on to step 1:
When dividing 1 by 871, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 871

Let's proceed to step 2:
15 divided by 871 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 871

Moving on to step 3:
If we divide 158 by 871, we get 0 and a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Fetch the next digit (7) from the dividend, attach it to 158 and continue: 1587 / 871

Moving on to step 4:
1587 divided by 871 is 1 with a remainder of 716.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 871 away from 1587, we end up with 716.
Take the next digit (2) from the dividend and append it to 716, then repeat: 7162 / 871

On to step 5:
The number 871 fits into 7162 8 times, leaving a remainder of 194.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 6968 from 7162 and we're left with 194.
Append the next digit (8) from the dividend to 194 and continue with: 1948 / 871

On to step 6:
When dividing 1948 by 871, we get 2 with a remainder of 206.
The next digit of our result is 2. 
Result so far: 182.0
Deduct 1742 from 1948 and we're left with 206.
Bring next digit (5) of the dividend behind the 206 and repeat the process: 2065 / 871

On to step 7:
871 goes into 2065 2 times with a remainder of 323.
The next digit of our result is 2. 
Result so far: 1822.0
If we take 1742 away from 2065, we end up with 323.
Bring next digit (0) of the dividend behind the 323 and repeat the process: 3230 / 871

Going ahead to step 8:
3230 divided by 871 is 3 with a remainder of 617.
Put 3 as the next digit of the answer. 
Result so far: 18223.0
Subtract 2613 from 3230 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 9:
If we divide 6170 by 871, we get 7 and a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 18223.7
The remainder is 73 after subtracting 6097 from 6170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
871 can be fit into 730 0 times, resulting in a remainder of 730.
Use 0 as the next digit of our solution. 
Result so far: 18223.7
Subtract 0 from 730 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 11:
If we divide 7300 by 871, we get 8 and a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 18223.708
Subtract 6968 from 7300 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 12:
871 can be fit into 3320 3 times, resulting in a remainder of 707.
The number 3 becomes the next digit in our result. 
Result so far: 18223.7083
Subtracting 2613 from 3320 leaves us with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Moving on to step 13:
871 can be fit into 7070 8 times, resulting in a remainder of 102.
The next digit of our result is 8. 
Result so far: 18223.70838
If we take 6968 away from 7070, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 14:
871 goes into 1020 1 times with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 18223.708381
Deduct 871 from 1020 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 15:
871 can be fit into 1490 1 times, resulting in a remainder of 619.
The next digit of our result is 1. 
Result so far: 18223.7083811
If we subtract 871 from 1490, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

In conclusion, the division gives 18223.7083811 with a balance of 6.19e-06.
