86418787 ÷ 85 
We want to divide 86418787 by 85.

Advancing to step 1:
85 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 85

Advancing to step 2:
85 can be fit into 86 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 85 from 86 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 85

Let's proceed to step 3:
85 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 85

Advancing to step 4:
If we divide 141 by 85, we get 1 and a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 85 from 141 to get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 85

Going ahead to step 5:
85 can be fit into 568 6 times, resulting in a remainder of 58.
The next digit of our result is 6. 
Result so far: 1016.0
If we subtract 510 from 568, we get 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 85

Going ahead to step 6:
85 can be fit into 587 6 times, resulting in a remainder of 77.
The next digit of our result is 6. 
Result so far: 10166.0
Subtract 510 from 587 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 85

Advancing to step 7:
85 can be fit into 778 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 101669.0
Subtracting 765 from 778 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 85

Going ahead to step 8:
If we divide 137 by 85, we get 1 and a remainder of 52.
The next digit of our result is 1. 
Result so far: 1016691.0
Deduct 85 from 137 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
85 goes into 520 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1016691.6
Deduct 510 from 520 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1016691.61
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1016691.611
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 1016691.611, and the remainder is 0.0065.
