495 divided by 871 is 0 with a remainder of 495.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 495 to get 495.
Bring next digit (9) of the dividend behind the 495 and repeat the process: 4959 / 871

On to step 6:
The number 871 fits into 4959 5 times, leaving a remainder of 604.
The next digit of our result is 5. 
Result so far: 205.0
The remainder is 604 after subtracting 4355 from 4959.
Include the next digit (4) from the dividend after 604, then repeat: 6044 / 871

On to step 7:
If we divide 6044 by 871, we get 6 and a remainder of 818.
The next digit of our result is 6. 
Result so far: 2056.0
Subtract 5226 from 6044 to get 818.
Include the next digit (4) from the dividend after 818, then repeat: 8184 / 871

Going ahead to step 8:
871 can be fit into 8184 9 times, resulting in a remainder of 345.
Use 9 as the next digit of our solution. 
Result so far: 20569.0
Subtracting 7839 from 8184 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
871 can be fit into 3450 3 times, resulting in a remainder of 837.
Use 3 as the next digit of our solution. 
Result so far: 20569.3
Deduct 2613 from 3450 and we're left with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Moving on to step 10:
871 goes into 8370 9 times with a remainder of 531.
Write down 9 as next digit of the result. 
Result so far: 20569.39
Deduct 7839 from 8370 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 11:
When dividing 5310 by 871, we get 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 20569.396
If we subtract 5226 from 5310, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
871 goes into 840 0 times with a remainder of 840.
The number 0 becomes the next digit in our result. 
Result so far: 20569.396
If we subtract 0 from 840, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 13:
When dividing 8400 by 871, we get 9 with a remainder of 561.
The next digit of our result is 9. 
Result so far: 20569.39609
Deduct 7839 from 8400 and we're left with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 14:
The number 871 fits into 5610 6 times, leaving a remainder of 384.
The next digit of our result is 6. 
Result so far: 20569.396096
If we take 5226 away from 5610, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
If we divide 3840 by 871, we get 4 and a remainder of 356.
The next digit of our result is 4. 
Result so far: 20569.3960964
Deduct 3484 from 3840 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 16:
871 can be fit into 3560 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 20569.39609644
Subtracting 3484 from 3560 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 20569.39609644, with a leftover of 7.6e-08.
