We look at the division of 268420 by 24 
The aim is to understand the frequency of 24 in 268420.

Let's proceed to step 1:
If we divide 2 by 24, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 24

Moving on to step 2:
24 goes into 26 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 24 away from 26, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 24

Moving on to step 3:
24 can be fit into 28 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 4 after subtracting 24 from 28.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 24

Let's proceed to step 4:
44 divided by 24 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 111.0
Subtract 24 from 44 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 24

Advancing to step 5:
24 goes into 202 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1118.0
The remainder is 10 after subtracting 192 from 202.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 24

Moving on to step 6:
24 can be fit into 100 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 11184.0
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
24 can be fit into 40 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 11184.1
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.

Step 8:
24 can be fit into 160 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 11184.16
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 24 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 11184.166
If we take 144 away from 160, we end up with 16.
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 result is 11184.166 with a remainder of 0.0016.
