We look at the division of 308422 by 25 
The aim is to understand the frequency of 25 in 308422.

Let's proceed to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 25

Step 2:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 25 away from 30, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 25

Advancing to step 3:
The number 25 fits into 58 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 50 from 58 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 25

Going ahead to step 4:
The number 25 fits into 84 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtract 75 from 84 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 25

Going ahead to step 5:
The number 25 fits into 92 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 1233.0
Deduct 75 from 92 and we're left with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 25

Advancing to step 6:
25 goes into 172 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 12336.0
Subtracting 150 from 172 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
25 goes into 220 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 12336.8
Deduct 200 from 220 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
25 can be fit into 200 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 12336.88
If we take 200 away from 200, 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.

In conclusion, the division gives 12336.88 with a balance of 0.0.
