757580 ÷ 25 
The aim is to understand the frequency of 25 in 757580.

Step 1:
If we divide 7 by 25, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 25

Step 2:
If we divide 75 by 25, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 75 from 75, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 25

Moving on to step 3:
When dividing 7 by 25, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 25

Moving on to step 4:
The number 25 fits into 75 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 303.0
If we take 75 away from 75, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 25

Let's proceed to step 5:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 3030.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 25

Advancing to step 6:
25 goes into 80 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 30303.0
If we subtract 75 from 80, we 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.

On to step 7:
If we divide 50 by 25, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 30303.2
If we subtract 50 from 50, 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 8:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30303.2
Subtract 0 from 0 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.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30303.2
Subtract 0 from 0 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.

Our division results in 30303.2 with a remaining 0.0.
