Let's divide 497570 by 25
The aim is to understand the frequency of 25 in 497570.

Moving on to step 1:
25 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 25

Moving on to step 2:
49 divided by 25 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 25 from 49 leaves us with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 25

Let's proceed to step 3:
247 divided by 25 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 225 from 247 to get 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 25

Step 4:
If we divide 225 by 25, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Subtracting 225 from 225 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 25

Step 5:
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: 1990.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 25

Let's proceed to step 6:
70 divided by 25 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 19902.0
The remainder is 20 after subtracting 50 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
25 can be fit into 200 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 19902.8
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.

Going ahead to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19902.8
If we take 0 away from 0, 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 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19902.8
Deduct 0 from 0 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.

In conclusion, the division gives 19902.8 with a balance of 0.0.
