868785 divided by 86 
We want to figure out the number of times 868785 can be divided by 86.

Step 1:
86 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 86

Step 2:
When dividing 86 by 86, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 86 away from 86, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 86

Let's proceed to step 3:
If we divide 8 by 86, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 86

Advancing to step 4:
If we divide 87 by 86, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 86 from 87 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 86

Let's proceed to step 5:
If we divide 18 by 86, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 1010.0
If we take 0 away from 18, we end up with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 86

Let's proceed to step 6:
86 goes into 185 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 10102.0
Subtracting 172 from 185 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 86, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 10102.1
Subtract 86 from 130 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10102.15
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 10102.151
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 86, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 10102.1511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 10102.1511 with a remaining 0.00054.
