We're dividing 243141 by 54 
Let's see how many times 54 fits into 243141.

Step 1:
54 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 54

On to step 2:
54 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 54

Moving on to step 3:
54 goes into 243 4 times with a remainder of 27.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 216 from 243 to get 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 54

Step 4:
The number 54 fits into 271 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 270 from 271 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 54

Going ahead to step 5:
54 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 450.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 54

Step 6:
54 can be fit into 141 2 times, resulting in a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 4502.0
The remainder is 33 after subtracting 108 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
The number 54 fits into 330 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4502.6
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
54 goes into 60 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 4502.61
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 54, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 4502.611
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4502.611 with a remainder of 0.0006.
