We look at the division of 508905 by 24 
The aim is to understand the frequency of 24 in 508905.

Advancing to step 1:
5 divided by 24 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 24

Let's proceed to step 2:
24 can be fit into 50 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 48 away from 50, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 24

Advancing to step 3:
28 divided by 24 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 24 from 28 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 24

Advancing to step 4:
When dividing 49 by 24, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
Subtract 48 from 49 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 24

Advancing to step 5:
When dividing 10 by 24, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2120.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 24

On to step 6:
105 divided by 24 is 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 21204.0
If we subtract 96 from 105, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
24 can be fit into 90 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 21204.3
Subtracting 72 from 90 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
24 can be fit into 180 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 21204.37
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 24 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21204.375
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.
Write down 0 as next digit of the result. 
Result so far: 21204.375
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.

Moving on to step 11:
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: 21204.375
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.

Our division results in 21204.375 with a remaining 0.0.
