Let's divide 121215 by 24
The aim is to understand the frequency of 24 in 121215.

Step 1:
1 divided by 24 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 24

Moving on to step 2:
12 divided by 24 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 24

Advancing to step 3:
When dividing 121 by 24, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 120 from 121 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 24

On to step 4:
24 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 24

Step 5:
If we divide 121 by 24, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 505.0
The remainder is 1 after subtracting 120 from 121.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 24

Moving on to step 6:
15 divided by 24 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 5050.0
If we subtract 0 from 15, 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.

Advancing to step 7:
150 divided by 24 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 5050.6
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.

Let's proceed to step 8:
60 divided by 24 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 5050.62
Subtracting 48 from 60 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 9:
24 goes into 120 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5050.625
Subtract 120 from 120 to 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.

Moving on to step 10:
If we divide 0 by 24, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5050.625
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.

Going ahead to step 11:
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: 5050.625
Subtracting 0 from 0 leaves us 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 5050.625 with a balance of 0.0.
