We're dividing 511697 by 75 
The aim is to understand the frequency of 75 in 511697.

Moving on to step 1:
5 divided by 75 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 75

Moving on to step 2:
The number 75 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 75

On to step 3:
511 divided by 75 is 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 61 after subtracting 450 from 511.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 75

Moving on to step 4:
616 divided by 75 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtract 600 from 616 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 75

Let's proceed to step 5:
When dividing 169 by 75, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 682.0
If we subtract 150 from 169, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 75

On to step 6:
The number 75 fits into 197 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 6822.0
The remainder is 47 after subtracting 150 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
75 can be fit into 470 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 6822.6
Subtract 450 from 470 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 75, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 6822.62
The remainder is 50 after subtracting 150 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 6822.626
The remainder is 50 after subtracting 450 from 500.
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 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6822.6266
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.

Our division results in 6822.6266 with a remaining 0.0005.
