86566712 divided by 871 
We want to divide 86566712 by 871.

On to step 1:
When dividing 8 by 871, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 871

Going ahead to step 2:
If we divide 86 by 871, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 871

Step 3:
When dividing 865 by 871, we get 0 with a remainder of 865.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 865 after subtracting 0 from 865.
Append the next digit (6) from the dividend to 865 and continue with: 8656 / 871

Step 4:
When dividing 8656 by 871, we get 9 with a remainder of 817.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7839 away from 8656, we end up with 817.
Bring next digit (6) of the dividend behind the 817 and repeat the process: 8176 / 871

Let's proceed to step 5:
8176 divided by 871 is 9 with a remainder of 337.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 7839 from 8176, we get 337.
Include the next digit (7) from the dividend after 337, then repeat: 3377 / 871

Step 6:
When dividing 3377 by 871, we get 3 with a remainder of 764.
The number 3 becomes the next digit in our result. 
Result so far: 993.0
If we take 2613 away from 3377, we end up with 764.
Take the next digit (1) from the dividend and append it to 764, then repeat: 7641 / 871

On to step 7:
871 can be fit into 7641 8 times, resulting in a remainder of 673.
The number 8 becomes the next digit in our result. 
Result so far: 9938.0
If we take 6968 away from 7641, we end up with 673.
Append the next digit (2) from the dividend to 673 and continue with: 6732 / 871

Let's proceed to step 8:
871 can be fit into 6732 7 times, resulting in a remainder of 635.
Write down 7 as next digit of the result. 
Result so far: 99387.0
Subtract 6097 from 6732 to get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 9:
When dividing 6350 by 871, we get 7 with a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 99387.7
Subtracting 6097 from 6350 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 10:
If we divide 2530 by 871, we get 2 and a remainder of 788.
Use 2 as the next digit of our solution. 
Result so far: 99387.72
If we take 1742 away from 2530, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

On to step 11:
7880 divided by 871 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 99387.729
Subtracting 7839 from 7880 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
410 divided by 871 is 0 with a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 99387.729
The remainder is 410 after subtracting 0 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 13:
871 can be fit into 4100 4 times, resulting in a remainder of 616.
Use 4 as the next digit of our solution. 
Result so far: 99387.72904
If we take 3484 away from 4100, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 14:
If we divide 6160 by 871, we get 7 and a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 99387.729047
If we subtract 6097 from 6160, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 15:
871 goes into 630 0 times with a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 99387.729047
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 16:
When dividing 6300 by 871, we get 7 with a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 99387.72904707
If we take 6097 away from 6300, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

In conclusion, the division gives 99387.72904707 with a balance of 2.03e-07.
