744735 divided by 75 
The aim is to understand the frequency of 75 in 744735.

On to step 1:
75 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 75

Step 2:
When dividing 74 by 75, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 75

Moving on to step 3:
If we divide 744 by 75, we get 9 and a remainder of 69.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 675 from 744, we get 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 75

Moving on to step 4:
When dividing 697 by 75, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 675 away from 697, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 75

Going ahead to step 5:
The number 75 fits into 223 2 times, leaving a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 992.0
If we subtract 150 from 223, we get 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 75

Step 6:
735 divided by 75 is 9 with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 9929.0
If we take 675 away from 735, we end up 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.

Let's proceed to step 7:
600 divided by 75 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 9929.8
The remainder is 0 after subtracting 600 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9929.8
Subtract 0 from 0 to 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 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9929.8
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.

The final result is 9929.8 with a remainder of 0.0.
