309532 divided by 24 
The aim is to understand the frequency of 24 in 309532.

On to step 1:
If we divide 3 by 24, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 24

On to step 2:
The number 24 fits into 30 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 24 from 30 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 24

On to step 3:
69 divided by 24 is 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 48 from 69 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 24

Step 4:
The number 24 fits into 215 8 times, leaving a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 192 from 215 and we're left with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 24

Going ahead to step 5:
233 divided by 24 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1289.0
Subtracting 216 from 233 leaves us with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 24

Step 6:
When dividing 172 by 24, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 12897.0
Subtracting 168 from 172 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 24 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 12897.1
Deduct 24 from 40 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 12897.16
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 12897.166
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 12897.166 with a remainder of 0.0016.
