We're dividing 483906 by 18 
The aim is to understand the frequency of 18 in 483906.

On to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Moving on to step 2:
18 can be fit into 48 2 times, resulting in 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.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Let's proceed to step 3:
18 can be fit into 123 6 times, resulting in a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 108 away from 123, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 18

Moving on to step 4:
If we divide 159 by 18, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 268.0
If we subtract 144 from 159, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 18

Advancing to step 5:
18 can be fit into 150 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2688.0
Subtracting 144 from 150 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 18

Advancing to step 6:
The number 18 fits into 66 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 26883.0
Subtracting 54 from 66 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.

On to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 26883.6
Subtract 108 from 120 to get 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:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 26883.66
If we take 108 away from 120, we end up 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.

In conclusion, the division gives 26883.66 with a balance of 0.012.
