We're dividing 54405 by 18 
We're looking to find how many times 18 goes into 54405.

Advancing to step 1:
5 divided by 18 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 18

Advancing to step 2:
54 divided by 18 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 54 from 54, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 18

Let's proceed to step 3:
When dividing 4 by 18, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 18

Step 4:
18 goes into 40 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 302.0
If we take 36 away from 40, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 18

Let's proceed to step 5:
45 divided by 18 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 3022.0
Deduct 36 from 45 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 6:
90 divided by 18 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3022.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3022.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 18 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3022.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3022.5, with a leftover of 0.0.
