We're dividing 150543 by 54 
We want to divide 150543 by 54.

On to step 1:
When dividing 1 by 54, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 54

Going ahead to step 2:
When dividing 15 by 54, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 54

On to step 3:
54 can be fit into 150 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 108 from 150, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 54

Step 4:
The number 54 fits into 425 7 times, leaving a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 378 away from 425, we end up with 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 54

Let's proceed to step 5:
54 goes into 474 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 278.0
The remainder is 42 after subtracting 432 from 474.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 54

Moving on to step 6:
The number 54 fits into 423 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 2787.0
If we subtract 378 from 423, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
If we divide 450 by 54, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 2787.8
Deduct 432 from 450 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 54, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 2787.83
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
54 goes into 180 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 2787.833
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 2787.833 with a remainder of 0.0018.
