We look at the division of 830017 by 75 
The aim is to understand the frequency of 75 in 830017.

Moving on to step 1:
75 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 75

Advancing to step 2:
When dividing 83 by 75, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 75 from 83 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 75

Moving on to step 3:
75 can be fit into 80 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 75 from 80 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 75

Step 4:
The number 75 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 50, we get 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 75

Step 5:
The number 75 fits into 501 6 times, leaving a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
Deduct 450 from 501 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 75

Moving on to step 6:
If we divide 517 by 75, we get 6 and a remainder of 67.
The next digit of our result is 6. 
Result so far: 11066.0
The remainder is 67 after subtracting 450 from 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
When dividing 670 by 75, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 11066.8
If we take 600 away from 670, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
75 can be fit into 700 9 times, resulting in a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 11066.89
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11066.893
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11066.8933
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.

The final outcome is 11066.8933, with a leftover of 0.00025.
