Let's divide 215418 by 24
The aim is to understand the frequency of 24 in 215418.

Going ahead to step 1:
24 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 24

Moving on to step 2:
The number 24 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 24

Step 3:
If we divide 215 by 24, we get 8 and a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 192 from 215, we get 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 24

Moving on to step 4:
When dividing 234 by 24, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtract 216 from 234 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 24

Moving on to step 5:
24 can be fit into 181 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 897.0
If we take 168 away from 181, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 24

Moving on to step 6:
24 can be fit into 138 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 8975.0
Subtracting 120 from 138 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 24 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 8975.7
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
24 can be fit into 120 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8975.75
Subtract 120 from 120 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.

Let's proceed to step 9:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8975.75
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.

Moving on to step 10:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8975.75
The remainder is 0 after subtracting 0 from 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 8975.75 with a remaining 0.0.
