546240 ÷ 18 
The aim is to understand the frequency of 18 in 546240.

Let's proceed to step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 18

Moving on to step 2:
18 goes into 54 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 54 from 54 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 18

On to step 3:
18 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 18

Let's proceed to step 4:
18 can be fit into 62 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 303.0
Subtract 54 from 62 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 18

Going ahead to step 5:
18 goes into 84 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3034.0
Subtract 72 from 84 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 18

Going ahead to step 6:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 30346.0
Subtracting 108 from 120 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.

Advancing to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 30346.6
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.

Let's proceed to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 30346.66
Deduct 108 from 120 and we're left 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 30346.66 with a balance of 0.012.
