We divide 533404 by 25
The aim is to understand the frequency of 25 in 533404.

Let's proceed to step 1:
25 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 25

Going ahead to step 2:
25 can be fit into 53 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 50 away from 53, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 25

Moving on to step 3:
25 goes into 33 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 25 from 33 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 25

Advancing to step 4:
When dividing 84 by 25, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtract 75 from 84 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 25

Going ahead to step 5:
25 can be fit into 90 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 2133.0
If we subtract 75 from 90, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 25

Step 6:
25 goes into 154 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 21336.0
If we take 150 away from 154, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 25 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 21336.1
Subtracting 25 from 40 leaves us with 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:
150 divided by 25 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 21336.16
If we take 150 away from 150, 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.

On 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: 21336.16
Deduct 0 from 0 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.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21336.16
Deduct 0 from 0 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.

The final result is 21336.16 with a remainder of 0.0.
