We divide 659634 by 25
The aim is to understand the frequency of 25 in 659634.

Let's proceed to step 1:
25 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 25

Let's proceed to step 2:
When dividing 65 by 25, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 50 from 65 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 25

Step 3:
If we divide 159 by 25, we get 6 and a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 150 from 159 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 25

Let's proceed to step 4:
The number 25 fits into 96 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 263.0
Subtract 75 from 96 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 25

Moving on to step 5:
If we divide 213 by 25, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 2638.0
The remainder is 13 after subtracting 200 from 213.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 25

Advancing to step 6:
When dividing 134 by 25, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 26385.0
Subtracting 125 from 134 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
25 can be fit into 90 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 26385.3
Deduct 75 from 90 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 25, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26385.36
Subtracting 150 from 150 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.

On to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26385.36
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.

Going ahead to step 10:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26385.36
If we subtract 0 from 0, 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.

In conclusion, the division gives 26385.36 with a balance of 0.0.
