We look at the division of 84427 by 25 
The aim is to understand the frequency of 25 in 84427.

Let's proceed to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 25

Step 2:
The number 25 fits into 84 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 75 from 84, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 25

On to step 3:
When dividing 94 by 25, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 33.0
If we take 75 away from 94, we end up with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 25

Advancing to step 4:
25 can be fit into 192 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 337.0
If we subtract 175 from 192, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 25

Let's proceed to step 5:
The number 25 fits into 177 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 3377.0
Deduct 175 from 177 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 6:
20 divided by 25 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3377.0
Subtract 0 from 20 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.

Advancing to step 7:
25 goes into 200 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3377.08
Deduct 200 from 200 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 8:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3377.08
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.

Step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3377.08
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.

After the division, we end up with 3377.08 and a remainder of 0.0.
