812388 divided by 24 
The aim is to understand the frequency of 24 in 812388.

On to 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
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 24

Advancing to step 2:
If we divide 81 by 24, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 72 from 81 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 24

Advancing to step 3:
If we divide 92 by 24, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 72 away from 92, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 24

On to step 4:
24 goes into 203 8 times with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
The remainder is 11 after subtracting 192 from 203.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 24

Step 5:
When dividing 118 by 24, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 3384.0
If we subtract 96 from 118, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 24

Going ahead to step 6:
The number 24 fits into 228 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 33849.0
Subtracting 216 from 228 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 24 fits into 120 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33849.5
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.

On to step 8:
The number 24 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 33849.5
If we take 0 away from 0, we end up 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 9:
When dividing 0 by 24, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33849.5
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.

In conclusion, the division gives 33849.5 with a balance of 0.0.
