We look at the division of 713380 by 25 
The aim is to understand the frequency of 25 in 713380.

On to step 1:
If we divide 7 by 25, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 25

Moving on to step 2:
71 divided by 25 is 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 50 from 71 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 25

Moving on to step 3:
25 goes into 213 8 times with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 13 after subtracting 200 from 213.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 25

On to step 4:
25 can be fit into 133 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 285.0
The remainder is 8 after subtracting 125 from 133.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 25

Going ahead to step 5:
The number 25 fits into 88 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 2853.0
If we subtract 75 from 88, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 25

Advancing to step 6:
25 can be fit into 130 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 28535.0
Subtract 125 from 130 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
25 can be fit into 50 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 28535.2
Subtract 50 from 50 to 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.

Let's proceed to step 8:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28535.2
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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28535.2
Subtracting 0 from 0 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.

Our division results in 28535.2 with a remaining 0.0.
