We look at the division of 463033 by 18 
The aim is to understand the frequency of 18 in 463033.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 18

Going ahead to step 2:
46 divided by 18 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 36 from 46, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 18

Step 3:
When dividing 103 by 18, we get 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 90 from 103 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 18

Step 4:
18 can be fit into 130 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 257.0
Subtracting 126 from 130 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

Going ahead to step 5:
18 goes into 43 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2572.0
If we subtract 36 from 43, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 18

Moving on to step 6:
If we divide 73 by 18, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 25724.0
Deduct 72 from 73 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
18 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 25724.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 18 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25724.05
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 25724.055
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 25724.055 and a remainder of 0.001.
