We look at the division of 80448 by 25 
The aim is to understand the frequency of 25 in 80448.

On to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 25

On to step 2:
80 divided by 25 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 80 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 25

Let's proceed to step 3:
54 divided by 25 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 50 from 54, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 25

Let's proceed to step 4:
25 goes into 44 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 321.0
Subtract 25 from 44 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 25

Going ahead to step 5:
The number 25 fits into 198 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 3217.0
Deduct 175 from 198 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 6:
When dividing 230 by 25, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 3217.9
If we subtract 225 from 230, we 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.

On to step 7:
The number 25 fits into 50 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3217.92
Deduct 50 from 50 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.

Let's proceed to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3217.92
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.

Going ahead to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3217.92
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.

The final result is 3217.92 with a remainder of 0.0.
