797547 ÷ 25 
The aim is to understand the frequency of 25 in 797547.

Moving on to step 1:
25 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 25

On to step 2:
79 divided by 25 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 4 after subtracting 75 from 79.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 25

Step 3:
The number 25 fits into 47 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 25 away from 47, we end up with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 25

Going ahead to step 4:
When dividing 225 by 25, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 319.0
If we take 225 away from 225, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 25

Let's proceed to step 5:
When dividing 4 by 25, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 3190.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 25

Advancing to step 6:
25 goes into 47 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 31901.0
Subtract 25 from 47 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 25, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 31901.8
The remainder is 20 after subtracting 200 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 31901.88
If we subtract 200 from 200, 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 outcome is 31901.88, with a leftover of 0.0.
