866536 ÷ 88 
We want to figure out the number of times 866536 can be divided by 88.

Step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 88

Moving on to step 2:
When dividing 86 by 88, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 88

Step 3:
The number 88 fits into 866 9 times, leaving a remainder of 74.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 792 from 866, we get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 88

Moving on to step 4:
745 divided by 88 is 8 with a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 704 from 745 and we're left with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 88

On to step 5:
413 divided by 88 is 4 with a remainder of 61.
The next digit of our result is 4. 
Result so far: 984.0
The remainder is 61 after subtracting 352 from 413.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 88

Let's proceed to step 6:
88 goes into 616 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 9847.0
The remainder is 0 after subtracting 616 from 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
88 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9847.0
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.

Step 8:
When dividing 0 by 88, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9847.0
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.

Our division results in 9847.0 with a remaining 0.0.
