487455 ÷ 25 
The aim is to understand the frequency of 25 in 487455.

Advancing to step 1:
4 divided by 25 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 25

Advancing to step 2:
25 goes into 48 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 25 from 48 and we're left with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 25

On to step 3:
When dividing 237 by 25, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 12 after subtracting 225 from 237.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 25

Advancing to step 4:
25 can be fit into 124 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
Subtracting 100 from 124 leaves us with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 25

On to step 5:
245 divided by 25 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1949.0
If we take 225 away from 245, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 25

Let's proceed to step 6:
25 can be fit into 205 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 19498.0
The remainder is 5 after subtracting 200 from 205.
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:
50 divided by 25 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 19498.2
If we take 50 away from 50, we end up 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.

Let's proceed to step 8:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19498.2
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.

Let's proceed to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19498.2
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.

In conclusion, the division gives 19498.2 with a balance of 0.0.
