We're dividing 52300122 by 25 
The aim is to understand the frequency of 25 in 52300122.

Going ahead to step 1:
When dividing 5 by 25, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 25

Let's proceed to step 2:
25 goes into 52 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 50 from 52, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 25

Advancing to step 3:
23 divided by 25 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 25

Advancing to step 4:
When dividing 230 by 25, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
If we take 225 away from 230, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 25

Step 5:
50 divided by 25 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2092.0
Subtract 50 from 50 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 25

Going ahead to step 6:
25 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20920.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 25

Advancing to step 7:
12 divided by 25 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 209200.0
If we subtract 0 from 12, we get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 25

On to step 8:
The number 25 fits into 122 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 2092004.0
If we take 100 away from 122, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
The number 25 fits into 220 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 2092004.8
Subtracting 200 from 220 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2092004.88
Deduct 200 from 200 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.

The final result is 2092004.88 with a remainder of 0.0.
