540426 ÷ 18 
We're looking to find how many times 18 goes into 540426.

Advancing to step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 18

Advancing to step 2:
The number 18 fits into 54 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 54 from 54.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 18

Moving on to step 3:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 18

Moving on to step 4:
4 divided by 18 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 300.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 18

Moving on to step 5:
If we divide 42 by 18, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3002.0
Deduct 36 from 42 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 18

Going ahead to step 6:
When dividing 66 by 18, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 30023.0
Deduct 54 from 66 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.

Step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 30023.6
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.

Moving on to step 8:
18 goes into 120 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 30023.66
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.

In conclusion, the division gives 30023.66 with a balance of 0.012.
