We look at the division of 356643 by 24 
The aim is to understand the frequency of 24 in 356643.

Going ahead to step 1:
24 goes into 3 0 times with 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 (5) of the dividend behind the 3 and repeat the process: 35 / 24

Advancing to step 2:
If we divide 35 by 24, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 24 away from 35, we end up with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 24

Moving on to step 3:
When dividing 116 by 24, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 96 from 116 to get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 24

Moving on to step 4:
24 goes into 206 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
The remainder is 14 after subtracting 192 from 206.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 24

Advancing to step 5:
24 goes into 144 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1486.0
If we take 144 away from 144, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 24

On to step 6:
When dividing 3 by 24, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 14860.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 24, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 14860.1
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 24, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 14860.12
If we take 48 away from 60, we end up 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.

Going ahead to step 9:
24 goes into 120 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14860.125
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.

On to step 10:
24 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14860.125
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.

On to step 11:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14860.125
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.

The final result is 14860.125 with a remainder of 0.0.
