We look at the division of 880517 by 75 
The aim is to understand the frequency of 75 in 880517.

Let's proceed to step 1:
75 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 75

Advancing to step 2:
75 goes into 88 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 75 from 88 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 75

On to step 3:
75 can be fit into 130 1 times, resulting in a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 75 from 130, we get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 75

Going ahead to step 4:
555 divided by 75 is 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 525 from 555 to get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 75

Moving on to step 5:
75 goes into 301 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 1174.0
Deduct 300 from 301 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 75

Let's proceed to step 6:
The number 75 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 11740.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 75 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 11740.2
Subtract 150 from 170 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.

Moving on to step 8:
75 can be fit into 200 2 times, resulting in a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 11740.22
Deduct 150 from 200 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.

The final outcome is 11740.22, with a leftover of 0.05.
