We look at the division of 30139 by 54 
We want to divide 30139 by 54.

On to step 1:
3 divided by 54 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 54

Step 2:
If we divide 30 by 54, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 54

On to step 3:
54 can be fit into 301 5 times, resulting in a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 270 from 301 to get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 54

Moving on to step 4:
When dividing 313 by 54, we get 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 270 from 313 and we're left with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 54

Advancing to step 5:
The number 54 fits into 439 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 558.0
The remainder is 7 after subtracting 432 from 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
If we divide 70 by 54, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 558.1
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
160 divided by 54 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 558.12
Subtract 108 from 160 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
520 divided by 54 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 558.129
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 54, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 558.1296
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 54 fits into 160 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 558.12962
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 54, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 558.129629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
54 can be fit into 340 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 558.1296296
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
160 divided by 54 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 558.12962962
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 558.12962962 and a remainder of 5.2e-08.
