We're dividing 253007 by 25 
The aim is to understand the frequency of 25 in 253007.

Going ahead to step 1:
If we divide 2 by 25, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 25

Step 2:
25 goes into 25 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 25 from 25 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 25

Let's proceed to step 3:
25 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 25

Step 4:
The number 25 fits into 30 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 25 away from 30, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 25

On to step 5:
The number 25 fits into 50 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1012.0
The remainder is 0 after subtracting 50 from 50.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 25

Advancing to step 6:
7 divided by 25 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10120.0
The remainder is 7 after subtracting 0 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
25 can be fit into 70 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 10120.2
Subtract 50 from 70 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 10120.28
Subtracting 200 from 200 leaves us 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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10120.28
If we subtract 0 from 0, 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:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10120.28
If we subtract 0 from 0, 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.

The final result is 10120.28 with a remainder of 0.0.
