We're dividing 721680 by 24 
The aim is to understand the frequency of 24 in 721680.

Step 1:
24 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 24

Step 2:
72 divided by 24 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 72 away from 72, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 24

Let's proceed to step 3:
The number 24 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 24

On to step 4:
The number 24 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 24

Moving on to step 5:
The number 24 fits into 168 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 3007.0
Subtract 168 from 168 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 24

Going ahead to step 6:
24 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30070.0
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 7:
24 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 30070.0
Subtracting 0 from 0 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.

Advancing to step 8:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30070.0
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.

Our division results in 30070.0 with a remaining 0.0.
