We're dividing 198168 by 25 
The aim is to understand the frequency of 25 in 198168.

Going ahead to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 25

Advancing to step 2:
The number 25 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 25

On to step 3:
If we divide 198 by 25, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 175 from 198 and we're left with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 25

Going ahead to step 4:
25 goes into 231 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 225 from 231 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 25

Let's proceed to step 5:
25 can be fit into 66 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 792.0
The remainder is 16 after subtracting 50 from 66.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 25

Advancing to step 6:
The number 25 fits into 168 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 7926.0
If we take 150 away from 168, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
25 can be fit into 180 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7926.7
Subtract 175 from 180 to 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.

Moving on to step 8:
25 can be fit into 50 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 7926.72
If we take 50 away from 50, 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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7926.72
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.

On to step 10:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7926.72
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 7926.72 with a balance of 0.0.
