Let's divide 170791 by 75
The aim is to understand the frequency of 75 in 170791.

Going ahead to step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 75

Let's proceed to step 2:
If we divide 17 by 75, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 75

Going ahead to step 3:
170 divided by 75 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 150 from 170 and we're left with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 75

Moving on to step 4:
If we divide 207 by 75, we get 2 and a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 150 from 207 leaves us with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 75

On to step 5:
When dividing 579 by 75, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 227.0
If we subtract 525 from 579, we get 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 75

Going ahead to step 6:
75 goes into 541 7 times with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 2277.0
If we take 525 away from 541, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 75 fits into 160 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2277.2
If we take 150 away from 160, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 75, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 2277.21
If we take 75 away from 100, we end up 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 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 2277.213
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.

Moving on to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 2277.2133
Deduct 225 from 250 and we're left 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 2277.2133, with a leftover of 0.00025.
