We look at the division of 563504 by 75 
The aim is to understand the frequency of 75 in 563504.

Moving on to step 1:
75 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 75

Moving on to step 2:
If we divide 56 by 75, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 75

Going ahead to step 3:
75 goes into 563 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 525 from 563 to get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 75

Step 4:
75 goes into 385 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 375 from 385, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 75

Going ahead to step 5:
The number 75 fits into 100 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 751.0
If we subtract 75 from 100, we get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 75

Advancing to step 6:
If we divide 254 by 75, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 7513.0
Subtract 225 from 254 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 75, we get 3 and a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 7513.3
If we subtract 225 from 290, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
If we divide 650 by 75, we get 8 and a remainder of 50.
The next digit of our result is 8. 
Result so far: 7513.38
Subtracting 600 from 650 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 7513.386
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 7513.3866
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 7513.3866 and a remainder of 0.0005.
