481003 ÷ 18 
The aim is to understand the frequency of 18 in 481003.

Advancing 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.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 18

Moving on to step 2:
18 goes into 48 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 36 from 48 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 18

Step 3:
The number 18 fits into 121 6 times, leaving a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 108 from 121 and we're left with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 18

Moving on to step 4:
130 divided by 18 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 267.0
The remainder is 4 after subtracting 126 from 130.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 18

Step 5:
40 divided by 18 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2672.0
Subtract 36 from 40 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

Going ahead to step 6:
If we divide 43 by 18, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 26722.0
The remainder is 7 after subtracting 36 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 18, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 26722.3
Deduct 54 from 70 and we're left 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.

Let's proceed to step 8:
160 divided by 18 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26722.38
Subtracting 144 from 160 leaves us 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.

Let's proceed to step 9:
160 divided by 18 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 26722.388
Deduct 144 from 160 and we're left 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 26722.388 with a remainder of 0.0016.
