We look at the division of 15416 by 24 
The aim is to understand the frequency of 24 in 15416.

On to step 1:
1 divided by 24 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 24

Step 2:
When dividing 15 by 24, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 24

Going ahead to step 3:
24 goes into 154 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 144 from 154 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 24

Let's proceed to step 4:
When dividing 101 by 24, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 96 from 101 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 24

Advancing to step 5:
If we divide 56 by 24, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
If we subtract 48 from 56, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
24 goes into 80 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 642.3
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 24 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 642.33
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 642.33, and the remainder is 0.008.
