We look at the division of 144978 by 3 
Our goal is to divide 144978 by 3.

Going ahead to step 1:
3 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 subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 12 from 14, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Going ahead to step 3:
If we divide 24 by 3, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 24 from 24, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Advancing to step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 483.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Moving on to step 5:
When dividing 7 by 3, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 4832.0
Subtracting 6 from 7 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Moving on to step 6:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 48326.0
Subtract 18 from 18 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.

Moving on to step 7:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48326.0
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.

On to step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48326.0
If we subtract 0 from 0, we 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 outcome is 48326.0, with a leftover of 0.0.
