We look at the division of 54030 by 84 
Let's see how many times 84 fits into 54030.

Going ahead to step 1:
The number 84 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 84

On to step 2:
84 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 84

Let's proceed to step 3:
The number 84 fits into 540 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 504 from 540 and we're left with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 84

Advancing to step 4:
When dividing 363 by 84, we get 4 with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 336 from 363 to get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 84

Going ahead to step 5:
270 divided by 84 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 643.0
If we take 252 away from 270, we end up 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.

Step 6:
If we divide 180 by 84, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 643.2
Deduct 168 from 180 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:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 643.21
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 643.214
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 643.2142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 643.21428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
The number 84 fits into 480 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 643.214285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 643.2142857
The remainder is 12 after subtracting 588 from 600.
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 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 643.21428571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 643.21428571 and a remainder of 3.6e-08.
