Let's divide 724480 by 75
The aim is to understand the frequency of 75 in 724480.

On to step 1:
The number 75 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 75

Step 2:
75 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 75

On to step 3:
75 can be fit into 724 9 times, resulting in a remainder of 49.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 675 from 724 to get 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 75

Moving on to step 4:
When dividing 494 by 75, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtracting 450 from 494 leaves us with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 75

Let's proceed to step 5:
448 divided by 75 is 5 with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
Subtract 375 from 448 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 75

Going ahead to step 6:
75 goes into 730 9 times with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 9659.0
If we subtract 675 from 730, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
The number 75 fits into 550 7 times, leaving a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 9659.7
If we subtract 525 from 550, 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.

Let's proceed to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9659.73
The remainder is 25 after subtracting 225 from 250.
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 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9659.733
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.

Our division results in 9659.733 with a remaining 0.0025.
