We look at the division of 109419 by 75 
The aim is to understand the frequency of 75 in 109419.

Going ahead to step 1:
When dividing 1 by 75, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 75

Step 2:
75 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 75

Going ahead to step 3:
If we divide 109 by 75, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 109, we get 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 75

Moving on to step 4:
344 divided by 75 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 300 from 344 and we're left with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 75

Advancing to step 5:
When dividing 441 by 75, we get 5 with a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtract 375 from 441 to get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 75

Let's proceed to step 6:
When dividing 669 by 75, we get 8 with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 1458.0
If we subtract 600 from 669, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
The number 75 fits into 690 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 1458.9
If we take 675 away from 690, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1458.92
If we subtract 150 from 150, we 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.

Step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1458.92
If we subtract 0 from 0, we 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.

Advancing to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1458.92
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.

In conclusion, the division gives 1458.92 with a balance of 0.0.
