Let's divide 240561 by 75
The aim is to understand the frequency of 75 in 240561.

On to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 75

Step 2:
The number 75 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 75

Going ahead to step 3:
When dividing 240 by 75, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 225 from 240, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 75

Moving on to step 4:
75 can be fit into 155 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 5 after subtracting 150 from 155.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 75

Advancing to step 5:
56 divided by 75 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
The remainder is 56 after subtracting 0 from 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 75

Moving on to step 6:
The number 75 fits into 561 7 times, leaving a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 3207.0
If we take 525 away from 561, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 75 fits into 360 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 3207.4
Subtracting 300 from 360 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
75 goes into 600 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 3207.48
If we subtract 600 from 600, 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.

Moving on to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3207.48
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.

Let's proceed to step 10:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3207.48
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.

The final result is 3207.48 with a remainder of 0.0.
