We look at the division of 86071489 by 871 
We want to divide 86071489 by 871.

Advancing to step 1:
871 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 871

Going ahead to step 2:
When dividing 86 by 871, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 871

Let's proceed to step 3:
If we divide 860 by 871, we get 0 and a remainder of 860.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 860 and we're left with 860.
Append the next digit (7) from the dividend to 860 and continue with: 8607 / 871

On to step 4:
871 goes into 8607 9 times with a remainder of 768.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7839 from 8607 to get 768.
Grab the next digit (1) from the dividend, add it to 768, then carry on: 7681 / 871

Moving on to step 5:
The number 871 fits into 7681 8 times, leaving a remainder of 713.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 6968 from 7681 leaves us with 713.
Take the next digit (4) from the dividend and append it to 713, then repeat: 7134 / 871

Advancing to step 6:
The number 871 fits into 7134 8 times, leaving a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 988.0
If we take 6968 away from 7134, we end up with 166.
Include the next digit (8) from the dividend after 166, then repeat: 1668 / 871

Going ahead to step 7:
871 can be fit into 1668 1 times, resulting in a remainder of 797.
Write down 1 as next digit of the result. 
Result so far: 9881.0
Subtract 871 from 1668 to get 797.
Include the next digit (9) from the dividend after 797, then repeat: 7979 / 871

Let's proceed to step 8:
If we divide 7979 by 871, we get 9 and a remainder of 140.
Use 9 as the next digit of our solution. 
Result so far: 98819.0
Subtract 7839 from 7979 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 9:
871 can be fit into 1400 1 times, resulting in a remainder of 529.
The next digit of our result is 1. 
Result so far: 98819.1
Subtract 871 from 1400 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 10:
5290 divided by 871 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 98819.16
Subtracting 5226 from 5290 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
The number 871 fits into 640 0 times, leaving a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 98819.16
If we subtract 0 from 640, we get 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:
6400 divided by 871 is 7 with a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 98819.1607
Subtracting 6097 from 6400 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 13:
871 can be fit into 3030 3 times, resulting in a remainder of 417.
Record the quotient 3 as the next digit in the result. 
Result so far: 98819.16073
Subtract 2613 from 3030 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 14:
871 can be fit into 4170 4 times, resulting in a remainder of 686.
Use 4 as the next digit of our solution. 
Result so far: 98819.160734
Subtracting 3484 from 4170 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 15:
When dividing 6860 by 871, we get 7 with a remainder of 763.
The next digit of our result is 7. 
Result so far: 98819.1607347
The remainder is 763 after subtracting 6097 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Advancing to step 16:
871 can be fit into 7630 8 times, resulting in a remainder of 662.
Write down 8 as next digit of the result. 
Result so far: 98819.16073478
Subtract 6968 from 7630 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

The final outcome is 98819.16073478, with a leftover of 6.62e-07.
