Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6968 from 7547 and we're left with 579.
Take the next digit (0) from the dividend and append it to 579, then repeat: 5790 / 871

Moving on to step 5:
If we divide 5790 by 871, we get 6 and a remainder of 564.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 564 after subtracting 5226 from 5790.
Append the next digit (1) from the dividend to 564 and continue with: 5641 / 871

Advancing to step 6:
871 goes into 5641 6 times with a remainder of 415.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
The remainder is 415 after subtracting 5226 from 5641.
Take the next digit (4) from the dividend and append it to 415, then repeat: 4154 / 871

Let's proceed to step 7:
When dividing 4154 by 871, we get 4 with a remainder of 670.
Put 4 as the next digit of the answer. 
Result so far: 8664.0
Deduct 3484 from 4154 and we're left with 670.
Take the next digit (9) from the dividend and append it to 670, then repeat: 6709 / 871

On to step 8:
When dividing 6709 by 871, we get 7 with a remainder of 612.
Put 7 as the next digit of the answer. 
Result so far: 86647.0
If we take 6097 away from 6709, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 9:
The number 871 fits into 6120 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 86647.7
Deduct 6097 from 6120 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
If we divide 230 by 871, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 86647.7
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
2300 divided by 871 is 2 with a remainder of 558.
Put 2 as the next digit of the answer. 
Result so far: 86647.702
If we subtract 1742 from 2300, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 12:
5580 divided by 871 is 6 with a remainder of 354.
Record the quotient 6 as the next digit in the result. 
Result so far: 86647.7026
The remainder is 354 after subtracting 5226 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 13:
871 goes into 3540 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 86647.70264
Deduct 3484 from 3540 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
560 divided by 871 is 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 86647.70264
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 15:
The number 871 fits into 5600 6 times, leaving a remainder of 374.
The number 6 becomes the next digit in our result. 
Result so far: 86647.7026406
If we take 5226 away from 5600, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 16:
871 can be fit into 3740 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 86647.70264064
Subtracting 3484 from 3740 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 86647.70264064 and a remainder of 2.56e-07.
