We look at the division of 722427 by 75 
The aim is to understand the frequency of 75 in 722427.

Advancing to step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 75

On to step 2:
75 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 75

On to step 3:
If we divide 722 by 75, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 675 from 722, we get 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 75

Advancing to step 4:
75 goes into 474 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 450 from 474 to get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 75

Step 5:
75 can be fit into 242 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 963.0
The remainder is 17 after subtracting 225 from 242.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 75

Moving on to step 6:
When dividing 177 by 75, we get 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 9632.0
If we take 150 away from 177, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
75 can be fit into 270 3 times, resulting in a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 9632.3
Subtract 225 from 270 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 75 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9632.36
If we subtract 450 from 450, we 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 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9632.36
If we subtract 0 from 0, we 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:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9632.36
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.

Our division results in 9632.36 with a remaining 0.0.
