We look at the division of 333342 by 25 
The aim is to understand the frequency of 25 in 333342.

Going ahead to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 25

Going ahead to step 2:
When dividing 33 by 25, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 25 away from 33, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 25

Step 3:
The number 25 fits into 83 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 75 from 83 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 25

Going ahead to step 4:
25 goes into 83 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 75 away from 83, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 25

Moving on to step 5:
When dividing 84 by 25, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1333.0
Deduct 75 from 84 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 25

Going ahead to step 6:
When dividing 92 by 25, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13333.0
If we subtract 75 from 92, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 25, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 13333.6
Subtract 150 from 170 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 13333.68
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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 13333.68
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.

On to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13333.68
Subtracting 0 from 0 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.

Our division results in 13333.68 with a remaining 0.0.
