We look at the division of 275950 by 75 
The aim is to understand the frequency of 75 in 275950.

Step 1:
2 divided by 75 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 75

Advancing to step 2:
When dividing 27 by 75, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 75

On to step 3:
275 divided by 75 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 225 from 275 leaves us with 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 75

Advancing to step 4:
If we divide 509 by 75, we get 6 and a remainder of 59.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 450 from 509 to get 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 75

Let's proceed to step 5:
The number 75 fits into 595 7 times, leaving a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 367.0
If we subtract 525 from 595, we get 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 75

Step 6:
When dividing 700 by 75, we get 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 3679.0
Subtracting 675 from 700 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.

Step 7:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 3679.3
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
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: 3679.33
If we subtract 225 from 250, we get 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 quotient of the division is 3679.33, and the remainder is 0.025.
