We look at the division of 23155 by 75 
The aim is to understand the frequency of 75 in 23155.

Step 1:
75 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 75

Step 2:
If we divide 23 by 75, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 75

Advancing to step 3:
When dividing 231 by 75, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 225 from 231 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 75

Advancing to step 4:
If we divide 65 by 75, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 65 after subtracting 0 from 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 75

Moving on to step 5:
75 goes into 655 8 times with a remainder of 55.
The next digit of our result is 8. 
Result so far: 308.0
The remainder is 55 after subtracting 600 from 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 6:
The number 75 fits into 550 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 308.7
Subtract 525 from 550 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
If we divide 250 by 75, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 308.73
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 308.733
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 308.733 with a remaining 0.0025.
