424472 divided by 18 
The aim is to understand the frequency of 18 in 424472.

Advancing to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 18

Let's proceed to step 2:
42 divided by 18 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 36 from 42 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

Going ahead to step 3:
64 divided by 18 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 54 from 64, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 18

Step 4:
When dividing 104 by 18, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 235.0
Deduct 90 from 104 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 18

Let's proceed to step 5:
When dividing 147 by 18, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 2358.0
Subtracting 144 from 147 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 18

Let's proceed to step 6:
18 goes into 32 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 23581.0
The remainder is 14 after subtracting 18 from 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 23581.7
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
18 goes into 140 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 23581.77
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 23581.77 with a remaining 0.014.
