127839 ÷ 30 
We want to figure out the number of times 127839 can be divided by 30.

Moving on to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

On to step 2:
30 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 30

Going ahead to step 3:
30 can be fit into 127 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 7 after subtracting 120 from 127.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 30

Advancing to step 4:
If we divide 78 by 30, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 60 from 78 to get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 30

Let's proceed to step 5:
30 can be fit into 183 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 426.0
If we take 180 away from 183, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 30

Let's proceed to step 6:
30 goes into 39 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 4261.0
If we take 30 away from 39, we end up 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 7:
30 can be fit into 90 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 4261.3
If we take 90 away from 90, 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.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4261.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4261.3
Subtract 0 from 0 to get 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 result is 4261.3 with a remainder of 0.0.
