We look at the division of 148260 by 30 
Let's see how many times 30 fits into 148260.

On to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 30

Advancing to step 2:
The number 30 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 30

Let's proceed to step 3:
30 can be fit into 148 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 28 after subtracting 120 from 148.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 30

Moving on to step 4:
The number 30 fits into 282 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 12 after subtracting 270 from 282.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 30

Going ahead to step 5:
If we divide 126 by 30, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 494.0
Subtract 120 from 126 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 30

Step 6:
30 goes into 60 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 4942.0
Subtracting 60 from 60 leaves us 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.

On to step 7:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4942.0
Deduct 0 from 0 and we're left 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.

Moving on to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4942.0
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 4942.0 with a remainder of 0.0.
