We divide 823 by 25
The aim is to understand the frequency of 25 in 823.

Let's proceed to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 25

Moving on to step 2:
If we divide 82 by 25, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 75 away from 82, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 25

Moving on to step 3:
73 divided by 25 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtracting 50 from 73 leaves us 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.

Moving on to step 4:
The number 25 fits into 230 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 32.9
Subtracting 225 from 230 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 5:
If we divide 50 by 25, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 32.92
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.

Going ahead to step 6:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32.92
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.

On to step 7:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32.92
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 quotient of the division is 32.92, and the remainder is 0.0.
