We're dividing 491980 by 24 
The aim is to understand the frequency of 24 in 491980.

Moving on to step 1:
If we divide 4 by 24, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 24

Advancing to step 2:
24 can be fit into 49 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 48 from 49 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 24

Advancing to step 3:
24 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 11, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 24

Step 4:
When dividing 119 by 24, we get 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 204.0
Deduct 96 from 119 and we're left with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 24

Advancing to step 5:
24 can be fit into 238 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 2049.0
If we take 216 away from 238, we end up with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 24

Moving on to step 6:
220 divided by 24 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 20499.0
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
24 can be fit into 40 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 20499.1
If we subtract 24 from 40, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
160 divided by 24 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 20499.16
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
The number 24 fits into 160 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 20499.166
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 20499.166, with a leftover of 0.0016.
