We look at the division of 662291 by 25 
The aim is to understand the frequency of 25 in 662291.

Moving on to step 1:
If we divide 6 by 25, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 25

Let's proceed to step 2:
If we divide 66 by 25, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 16 after subtracting 50 from 66.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 25

Moving on to step 3:
25 goes into 162 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 150 from 162 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 25

Going ahead to step 4:
25 goes into 122 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 264.0
The remainder is 22 after subtracting 100 from 122.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 25

Going ahead to step 5:
The number 25 fits into 229 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 2649.0
If we subtract 225 from 229, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 25

On to step 6:
41 divided by 25 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 26491.0
Deduct 25 from 41 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 25, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 26491.6
The remainder is 10 after subtracting 150 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
25 goes into 100 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 26491.64
If we subtract 100 from 100, 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.

Going ahead to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26491.64
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.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26491.64
The remainder is 0 after subtracting 0 from 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 26491.64 with a balance of 0.0.
