We look at the division of 86357 by 85 
Let's see how many times 85 fits into 86357.

Step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 85

Going ahead to step 2:
When dividing 86 by 85, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 85 from 86 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 85

Let's proceed to step 3:
When dividing 13 by 85, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 85

Advancing to step 4:
85 can be fit into 135 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 85 from 135 to get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 85

On to step 5:
85 goes into 507 5 times with a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
Deduct 425 from 507 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 6:
820 divided by 85 is 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 1015.9
The remainder is 55 after subtracting 765 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
550 divided by 85 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 1015.96
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
85 can be fit into 400 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 1015.964
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 85, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 1015.9647
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1015.9647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
85 goes into 500 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 1015.964705
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 1015.9647058
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
700 divided by 85 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 1015.96470588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1015.96470588 with a remaining 2e-08.
