Let's divide 86880 by 9
We want to figure out the number of times 86880 can be divided by 9.

Step 1:
9 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 9

Moving on to step 2:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 81 away from 86, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 9

Let's proceed to step 3:
When dividing 58 by 9, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtracting 54 from 58 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 9

Advancing to step 4:
When dividing 48 by 9, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 965.0
If we take 45 away from 48, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Moving on to step 5:
9 goes into 30 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 9653.0
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
When dividing 30 by 9, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 9653.3
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 9653.33
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 9653.33, and the remainder is 0.003.
