Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 857

Advancing to step 2:
If we divide 83 by 857, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (3) from the dividend, attach it to 83 and continue: 833 / 857

Moving on to step 3:
857 goes into 833 0 times with a remainder of 833.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 833 to get 833.

On to step 4:
8339 divided by 857 is 9 with a remainder of 626.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7713 from 8339 and we're left with 626.
Include the next digit (7) from the dividend after 626, then repeat: 6267 / 857

Going ahead to step 5:
857 goes into 6267 7 times with a remainder of 268.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 5999 from 6267, we get 268.
Fetch the next digit (0) from the dividend, attach it to 268 and continue: 2680 / 857

Moving on to step 6:
857 goes into 2680 3 times with a remainder of 109.
Use 3 as the next digit of our solution. 
Result so far: 973.0
Subtracting 2571 from 2680 leaves us with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 857

Moving on to step 7:
The number 857 fits into 1099 1 times, leaving a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 9731.0
If we subtract 857 from 1099, we get 242.
Include the next digit (1) from the dividend after 242, then repeat: 2421 / 857

Moving on to step 8:
857 can be fit into 2421 2 times, resulting in a remainder of 707.
The next digit of our result is 2. 
Result so far: 97312.0
Subtracting 1714 from 2421 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.

Let's proceed to step 9:
When dividing 7070 by 857, we get 8 with a remainder of 214.
The next digit of our result is 8. 
Result so far: 97312.8
The remainder is 214 after subtracting 6856 from 7070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
2140 divided by 857 is 2 with a remainder of 426.
Use 2 as the next digit of our solution. 
Result so far: 97312.82
Subtracting 1714 from 2140 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 11:
4260 divided by 857 is 4 with a remainder of 832.
Use 4 as the next digit of our solution. 
Result so far: 97312.824
Subtracting 3428 from 4260 leaves us with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Advancing to step 12:
The number 857 fits into 8320 9 times, leaving a remainder of 607.
Use 9 as the next digit of our solution. 
Result so far: 97312.8249
Deduct 7713 from 8320 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 13:
When dividing 6070 by 857, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 97312.82497
Subtracting 5999 from 6070 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 14:
857 can be fit into 710 0 times, resulting in a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 97312.82497
The remainder is 710 after subtracting 0 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 15:
857 can be fit into 7100 8 times, resulting in a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 97312.8249708
Subtracting 6856 from 7100 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 16:
When dividing 2440 by 857, we get 2 with a remainder of 726.
Write down 2 as next digit of the result. 
Result so far: 97312.82497082
The remainder is 726 after subtracting 1714 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

In conclusion, the division gives 97312.82497082 with a balance of 7.26e-07.
