We divide 86311359 by 24
The aim is to understand the frequency of 24 in 86311359.

Moving on to step 1:
When dividing 8 by 24, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 24

Advancing to step 2:
24 can be fit into 86 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 72 from 86, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 24

On to step 3:
24 goes into 143 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 120 away from 143, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 24

Let's proceed to step 4:
24 can be fit into 231 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 359.0
Deduct 216 from 231 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 24

Let's proceed to step 5:
24 goes into 151 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 3596.0
If we subtract 144 from 151, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 24

Step 6:
24 goes into 73 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 35963.0
If we take 72 away from 73, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 24

On to step 7:
24 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 359630.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 24

Going ahead to step 8:
159 divided by 24 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 3596306.0
If we subtract 144 from 159, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
24 goes into 150 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 3596306.6
Deduct 144 from 150 and we're left 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.

Advancing to step 10:
60 divided by 24 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3596306.62
Subtract 48 from 60 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 24, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3596306.625
The remainder is 0 after subtracting 120 from 120.
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 12:
0 divided by 24 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3596306.625
Deduct 0 from 0 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.

Advancing to step 13:
If we divide 0 by 24, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3596306.625
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.

After the division, we end up with 3596306.625 and a remainder of 0.0.
