We look at the division of 141783 by 75 
The aim is to understand the frequency of 75 in 141783.

Advancing to step 1:
75 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 75

Going ahead to step 2:
14 divided by 75 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 75

Step 3:
141 divided by 75 is 1 with a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 75 from 141 leaves us with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 75

Advancing to step 4:
The number 75 fits into 667 8 times, leaving a remainder of 67.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 600 from 667, we get 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 75

Going ahead to step 5:
If we divide 678 by 75, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
Deduct 675 from 678 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 75

Advancing to step 6:
When dividing 33 by 75, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 1890.0
Deduct 0 from 33 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
75 can be fit into 330 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 1890.4
Subtracting 300 from 330 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 75, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1890.44
Subtracting 300 from 300 leaves us 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 outcome is 1890.44, with a leftover of 0.0.
