We're dividing 658271 by 25 
The aim is to understand the frequency of 25 in 658271.

Moving on to step 1:
When dividing 6 by 25, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 25

Let's proceed to step 2:
The number 25 fits into 65 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 50 from 65 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 25

Step 3:
If we divide 158 by 25, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 150 from 158 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 25

Going ahead to step 4:
If we divide 82 by 25, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 263.0
If we subtract 75 from 82, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 25

Going ahead to step 5:
If we divide 77 by 25, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 2633.0
Subtract 75 from 77 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 25

On to step 6:
25 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 26330.0
Subtracting 0 from 21 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
25 can be fit into 210 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 26330.8
Deduct 200 from 210 and we're left with 10.
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:
When dividing 100 by 25, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 26330.84
The remainder is 0 after subtracting 100 from 100.
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 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26330.84
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.

Advancing to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26330.84
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.

Our division results in 26330.84 with a remaining 0.0.
