86616 divided by 15 
We want to figure out the number of times 86616 can be divided by 15.

Step 1:
15 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

Moving on to step 2:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 75 away from 86, we end up with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 15

Moving on to step 3:
When dividing 116 by 15, we get 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 105 from 116 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 15

Moving on to step 4:
The number 15 fits into 111 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 577.0
Subtract 105 from 111 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 15

On to step 5:
15 can be fit into 66 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5774.0
Subtracting 60 from 66 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
15 goes into 60 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 5774.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
15 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5774.4
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
15 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5774.4
If we subtract 0 from 0, we 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.

The quotient of the division is 5774.4, and the remainder is 0.0.
