We look at the division of 910925 by 75 
The aim is to understand the frequency of 75 in 910925.

Advancing to step 1:
75 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 75

Moving on to step 2:
91 divided by 75 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 75 away from 91, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 75

Moving on to step 3:
75 goes into 160 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 150 from 160 and we're left with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 75

Going ahead to step 4:
109 divided by 75 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
The remainder is 34 after subtracting 75 from 109.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 75

Step 5:
75 goes into 342 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
Subtract 300 from 342 to get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 75

Let's proceed to step 6:
The number 75 fits into 425 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12145.0
Deduct 375 from 425 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.

Moving on to step 7:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 12145.6
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.

Let's proceed to step 8:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 12145.66
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.

The final result is 12145.66 with a remainder of 0.05.
