Let's divide 860689 by 86
Our goal is to divide 860689 by 86.

On to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 86

Let's proceed to step 2:
The number 86 fits into 86 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 86 from 86.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 86

On to step 3:
0 divided by 86 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 86

Advancing to step 4:
86 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 86

Moving on to step 5:
If we divide 68 by 86, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
Subtract 0 from 68 to get 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 86

Step 6:
689 divided by 86 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 10008.0
If we subtract 688 from 689, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 86 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10008.0
If we subtract 0 from 10, 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.

Moving on to step 8:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 10008.01
Subtracting 86 from 100 leaves us 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 9:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 10008.011
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 10008.011 with a remainder of 0.0054.
