Let's divide 48420 by 25
The aim is to understand the frequency of 25 in 48420.

Advancing to step 1:
4 divided by 25 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 25

Let's proceed to step 2:
When dividing 48 by 25, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 25 from 48 to get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 25

Going ahead to step 3:
If we divide 234 by 25, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 225 from 234 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 25

Step 4:
25 can be fit into 92 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Subtract 75 from 92 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 25

On to step 5:
170 divided by 25 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1936.0
Deduct 150 from 170 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.

On to step 6:
200 divided by 25 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1936.8
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.

Let's proceed 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: 1936.8
The remainder is 0 after subtracting 0 from 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 8:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1936.8
The remainder is 0 after subtracting 0 from 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 1936.8, and the remainder is 0.0.
