Let's divide 86218856 by 24
We're looking to find how many times 24 goes into 86218856.

Step 1:
8 divided by 24 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 24

Advancing to step 2:
24 goes into 86 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 72 from 86 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 24

Moving on to step 3:
24 can be fit into 142 5 times, resulting in a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 120 from 142 to get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 24

Moving on to step 4:
24 can be fit into 221 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 359.0
Subtract 216 from 221 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 24

Moving on to step 5:
24 goes into 58 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 3592.0
The remainder is 10 after subtracting 48 from 58.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 24

Moving on to step 6:
The number 24 fits into 108 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 35924.0
Subtracting 96 from 108 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 24

Let's proceed to step 7:
125 divided by 24 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 359245.0
The remainder is 5 after subtracting 120 from 125.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 24

Advancing to step 8:
If we divide 56 by 24, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 3592452.0
If we subtract 48 from 56, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 24 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3592452.3
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3592452.33
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 3592452.33 with a remainder of 0.008.
