144039 divided by 31 
We want to divide 144039 by 31.

Step 1:
31 can be fit into 1 0 times, resulting in 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.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 31

Advancing to step 2:
When dividing 14 by 31, we get 0 with 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.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 31

Advancing to step 3:
If we divide 144 by 31, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 124 away from 144, we end up with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 31

Moving on to step 4:
31 can be fit into 200 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 186 from 200 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 31

Let's proceed to step 5:
31 can be fit into 143 4 times, resulting in a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 464.0
Subtracting 124 from 143 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 31

On to step 6:
The number 31 fits into 199 6 times, leaving a remainder of 13.
The next digit of our result is 6. 
Result so far: 4646.0
Subtract 186 from 199 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 31, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4646.4
Subtract 124 from 130 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4646.41
If we take 31 away from 60, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
31 goes into 290 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4646.419
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
31 can be fit into 110 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 4646.4193
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
31 can be fit into 170 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4646.41935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4646.419354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 31, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 4646.4193548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
31 goes into 120 3 times with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 4646.41935483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 4646.41935483 with a remainder of 2.7e-08.
