We look at the division of 299666 by 25 
The aim is to understand the frequency of 25 in 299666.

Going ahead to step 1:
2 divided by 25 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 25

Moving on to step 2:
The number 25 fits into 29 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 25 from 29 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 25

Going ahead to step 3:
25 can be fit into 49 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 25 away from 49, we end up with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 25

Going ahead to step 4:
The number 25 fits into 246 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 225 from 246 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 25

Step 5:
25 can be fit into 216 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1198.0
Subtracting 200 from 216 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 25

Moving on to step 6:
25 goes into 166 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 11986.0
Subtract 150 from 166 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 25 fits into 160 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 11986.6
Deduct 150 from 160 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.

On to step 8:
100 divided by 25 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 11986.64
Subtracting 100 from 100 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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11986.64
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11986.64
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.

In conclusion, the division gives 11986.64 with a balance of 0.0.
