We're dividing 653995 by 25 
The aim is to understand the frequency of 25 in 653995.

Moving on to step 1:
25 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 25

Advancing to step 2:
65 divided by 25 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 50 from 65, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 25

Advancing to step 3:
153 divided by 25 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 3 after subtracting 150 from 153.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 25

Advancing to step 4:
When dividing 39 by 25, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 261.0
Subtract 25 from 39 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 25

Going ahead to step 5:
149 divided by 25 is 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 2615.0
Subtract 125 from 149 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 25

Let's proceed to step 6:
245 divided by 25 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 26159.0
Subtracting 225 from 245 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.

Let's proceed to step 7:
25 goes into 200 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 26159.8
If we subtract 200 from 200, 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.

Step 8:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26159.8
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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26159.8
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.

The final outcome is 26159.8, with a leftover of 0.0.
