We look at the division of 144770 by 30 
Let's see how many times 30 fits into 144770.

On to step 1:
30 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 30

Let's proceed to step 2:
30 can be fit into 14 0 times, resulting in 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.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 30

Going ahead to step 3:
144 divided by 30 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 120 from 144 and we're left with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 30

Step 4:
The number 30 fits into 247 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 240 from 247 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 30

On to step 5:
If we divide 77 by 30, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 482.0
Subtracting 60 from 77 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 30

Step 6:
When dividing 170 by 30, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4825.0
Deduct 150 from 170 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4825.6
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4825.66
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 4825.66 and a remainder of 0.02.
