868557 divided by 86 
Our goal is to divide 868557 by 86.

Let's proceed to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
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 / 86

Step 2:
If we divide 86 by 86, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 86 from 86, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 86

Moving on to step 3:
If we divide 8 by 86, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 86

On to step 4:
If we divide 85 by 86, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (5) from the dividend, attach it to 85 and continue: 855 / 86

Let's proceed to step 5:
86 goes into 855 9 times with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 1009.0
Subtract 774 from 855 to get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 86

Going ahead to step 6:
If we divide 817 by 86, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 10099.0
Subtracting 774 from 817 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
86 goes into 430 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10099.5
Deduct 430 from 430 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 86 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10099.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
86 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10099.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10099.5 and a remainder of 0.0.
