80472 divided by 25 
The aim is to understand the frequency of 25 in 80472.

Step 1:
8 divided by 25 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 25

Advancing to step 2:
25 can be fit into 80 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 75 from 80 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 25

Let's proceed to step 3:
25 can be fit into 54 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 50 from 54, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 25

Let's proceed to step 4:
25 can be fit into 47 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
Subtract 25 from 47 to get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 25

Advancing to step 5:
25 goes into 222 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 3218.0
Subtract 200 from 222 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 6:
The number 25 fits into 220 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 3218.8
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.

Step 7:
If we divide 200 by 25, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3218.88
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.

After the division, we end up with 3218.88 and a remainder of 0.0.
