We divide 144137 by 3
We're looking to find how many times 3 goes into 144137.

Going ahead to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Moving on to step 2:
3 goes into 14 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Step 3:
24 divided by 3 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Going ahead to step 4:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 480.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Going ahead to step 5:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4804.0
If we subtract 12 from 13, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Going ahead to step 6:
3 goes into 17 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 48045.0
Subtract 15 from 17 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 48045.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 48045.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 48045.66, with a leftover of 0.002.
