120999 divided by 24 
The aim is to understand the frequency of 24 in 120999.

Moving on to step 1:
1 divided by 24 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 24

Moving on to step 2:
If we divide 12 by 24, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 24

Let's proceed to step 3:
When dividing 120 by 24, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 120 from 120 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 24

Advancing to step 4:
The number 24 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 24

On to step 5:
If we divide 99 by 24, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 504.0
If we subtract 96 from 99, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 24

Let's proceed to step 6:
When dividing 39 by 24, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 5041.0
If we subtract 24 from 39, 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 7:
24 goes into 150 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5041.6
Subtracting 144 from 150 leaves us 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.

Going ahead to step 8:
The number 24 fits into 60 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 5041.62
Deduct 48 from 60 and we're left 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 can be fit into 120 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5041.625
If we subtract 120 from 120, 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.

Moving on to step 10:
0 divided by 24 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5041.625
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.

On to step 11:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5041.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 5041.625 with a remainder of 0.0.
