We're dividing 859929 by 86 
Our goal is to divide 859929 by 86.

On to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Moving on to step 2:
The number 86 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 86

Going ahead to step 3:
When dividing 859 by 86, we get 9 with a remainder of 85.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 774 from 859, we get 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 86

Going ahead to step 4:
When dividing 859 by 86, we get 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 774 from 859, we get 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 86

On to step 5:
86 can be fit into 852 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 999.0
If we subtract 774 from 852, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 86

On to step 6:
789 divided by 86 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9999.0
If we take 774 away from 789, we end up with 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 7:
If we divide 150 by 86, we get 1 and a remainder of 64.
The next digit of our result is 1. 
Result so far: 9999.1
Subtracting 86 from 150 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
If we divide 640 by 86, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 9999.17
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
86 goes into 380 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9999.174
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
360 divided by 86 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9999.1744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 9999.1744 with a remaining 0.00016.
