We look at the division of 424341 by 75 
The aim is to understand the frequency of 75 in 424341.

Step 1:
75 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 75

Moving on to step 2:
The number 75 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 75

Advancing to step 3:
The number 75 fits into 424 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 375 from 424 to get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 75

On to step 4:
If we divide 493 by 75, we get 6 and a remainder of 43.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 450 from 493 leaves us with 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 75

Advancing to step 5:
75 goes into 434 5 times with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 565.0
The remainder is 59 after subtracting 375 from 434.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 75

Let's proceed to step 6:
If we divide 591 by 75, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 5657.0
If we take 525 away from 591, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
The number 75 fits into 660 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 5657.8
Subtracting 600 from 660 leaves us 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:
If we divide 600 by 75, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 5657.88
Deduct 600 from 600 and we're left 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 quotient of the division is 5657.88, and the remainder is 0.0.
