We divide 427884 by 25
The aim is to understand the frequency of 25 in 427884.

Step 1:
25 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 25

Step 2:
25 can be fit into 42 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 25 from 42, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 25

Step 3:
25 goes into 177 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 175 from 177, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 25

On to step 4:
28 divided by 25 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 171.0
If we take 25 away from 28, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 25

On to step 5:
When dividing 38 by 25, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1711.0
Subtracting 25 from 38 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 25

Advancing to step 6:
25 goes into 134 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 17115.0
If we take 125 away from 134, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 25, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 17115.3
Subtract 75 from 90 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
If we divide 150 by 25, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 17115.36
The remainder is 0 after subtracting 150 from 150.
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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17115.36
If we take 0 away from 0, 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.

Going ahead to step 10:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17115.36
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.

The final result is 17115.36 with a remainder of 0.0.
