We look at the division of 688998 by 24 
The aim is to understand the frequency of 24 in 688998.

Advancing to step 1:
The number 24 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 24

Let's proceed to step 2:
When dividing 68 by 24, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 48 away from 68, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 24

On to step 3:
24 can be fit into 208 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 192 away from 208, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 24

Going ahead to step 4:
169 divided by 24 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtracting 168 from 169 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 24

Advancing to step 5:
If we divide 19 by 24, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 2870.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 24

Let's proceed to step 6:
24 can be fit into 198 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 28708.0
If we subtract 192 from 198, we 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.

Step 7:
60 divided by 24 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 28708.2
The remainder is 12 after subtracting 48 from 60.
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 8:
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: 28708.25
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.

Advancing to step 9:
24 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28708.25
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.

Step 10:
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: 28708.25
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 28708.25 with a remainder of 0.0.
