We look at the division of 24979787 by 252 
The aim is to understand the frequency of 252 in 24979787.

Step 1:
The number 252 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 252

Step 2:
24 divided by 252 is 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 252

Step 3:
252 goes into 249 0 times with a remainder of 249.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 249 after subtracting 0 from 249.
Fetch the next digit (7) from the dividend, attach it to 249 and continue: 2497 / 252

Moving on to step 4:
The number 252 fits into 2497 9 times, leaving a remainder of 229.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 2268 from 2497, we get 229.
Take the next digit (9) from the dividend and append it to 229, then repeat: 2299 / 252

Moving on to step 5:
When dividing 2299 by 252, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 2268 from 2299 to get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 252

Advancing to step 6:
317 divided by 252 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
Subtracting 252 from 317 leaves us with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 252

On to step 7:
When dividing 658 by 252, we get 2 with a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 9912.0
The remainder is 154 after subtracting 504 from 658.
Take the next digit (7) from the dividend and append it to 154, then repeat: 1547 / 252

Step 8:
1547 divided by 252 is 6 with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 99126.0
If we take 1512 away from 1547, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
When dividing 350 by 252, we get 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 99126.1
The remainder is 98 after subtracting 252 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
When dividing 980 by 252, we get 3 with a remainder of 224.
The next digit of our result is 3. 
Result so far: 99126.13
Subtracting 756 from 980 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
When dividing 2240 by 252, we get 8 with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 99126.138
Subtracting 2016 from 2240 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 12:
252 can be fit into 2240 8 times, resulting in a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 99126.1388
The remainder is 224 after subtracting 2016 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 99126.1388 with a remaining 0.00224.
