We're dividing 422568 by 25 
The aim is to understand the frequency of 25 in 422568.

Moving on to step 1:
When dividing 4 by 25, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 25

Going ahead to step 2:
25 can be fit into 42 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 25 from 42 to get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 25

Moving on to step 3:
25 goes into 172 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 22 after subtracting 150 from 172.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 25

Let's proceed to step 4:
When dividing 225 by 25, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 225 from 225, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 25

On to step 5:
When dividing 6 by 25, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 1690.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 25

Advancing to step 6:
68 divided by 25 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 16902.0
If we subtract 50 from 68, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 25 fits into 180 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 16902.7
If we take 175 away from 180, we end up 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.

Going ahead to step 8:
25 goes into 50 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 16902.72
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.

Step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16902.72
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.

Let's proceed 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: 16902.72
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 quotient of the division is 16902.72, and the remainder is 0.0.
