We look at the division of 604853 by 75 
The aim is to understand the frequency of 75 in 604853.

Step 1:
75 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 75

Going ahead to step 2:
60 divided by 75 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 75

Let's proceed to step 3:
When dividing 604 by 75, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 600 from 604 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 75

Let's proceed to step 4:
The number 75 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 48 leaves us with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 75

Let's proceed to step 5:
75 goes into 485 6 times with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 806.0
Deduct 450 from 485 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 75

Advancing to step 6:
75 can be fit into 353 4 times, resulting in a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 8064.0
Subtract 300 from 353 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
75 goes into 530 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 8064.7
Deduct 525 from 530 and we're left 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.

Let's proceed to step 8:
If we divide 50 by 75, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8064.7
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
75 goes into 500 6 times with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 8064.706
Deduct 450 from 500 and we're left 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.

Step 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 8064.7066
If we subtract 450 from 500, we 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 8064.7066 and a remainder of 0.0005.
