We're dividing 910761 by 75 
The aim is to understand the frequency of 75 in 910761.

Step 1:
75 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 75

Going ahead to step 2:
75 goes into 91 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 75 from 91 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 75

Moving on to step 3:
When dividing 160 by 75, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 150 from 160, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 75

On to step 4:
The number 75 fits into 107 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 75 from 107 to get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 75

Step 5:
75 can be fit into 326 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 1214.0
If we take 300 away from 326, we end up with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 75

Let's proceed to step 6:
261 divided by 75 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 12143.0
Subtracting 225 from 261 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
75 goes into 360 4 times with a remainder of 60.
The next digit of our result is 4. 
Result so far: 12143.4
If we take 300 away from 360, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
The number 75 fits into 600 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 12143.48
Subtract 600 from 600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12143.48
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
75 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12143.48
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12143.48 with a remainder of 0.0.
