168208 divided by 25 
The aim is to understand the frequency of 25 in 168208.

On to step 1:
When dividing 1 by 25, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 25

On to step 2:
When dividing 16 by 25, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 25

On to step 3:
The number 25 fits into 168 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 150 from 168 leaves us with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 25

On to step 4:
25 goes into 182 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 67.0
The remainder is 7 after subtracting 175 from 182.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 25

Going ahead to step 5:
25 goes into 70 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 672.0
If we take 50 away from 70, we end up with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 25

Moving on to step 6:
25 goes into 208 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6728.0
Subtracting 200 from 208 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 25, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 6728.3
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 6728.32
Subtract 50 from 50 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.

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: 6728.32
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.

Step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6728.32
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.

The final outcome is 6728.32, with a leftover of 0.0.
