We're dividing 14903940 by 343 
Let's see how many times 343 fits into 14903940.

Going ahead to step 1:
1 divided by 343 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 343

On to step 2:
If we divide 14 by 343, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 343

Advancing to step 3:
343 goes into 149 0 times with a remainder of 149.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 149 and we're left with 149.
Include the next digit (0) from the dividend after 149, then repeat: 1490 / 343

Step 4:
343 goes into 1490 4 times with a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1372 from 1490 to get 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 343

Going ahead to step 5:
343 goes into 1183 3 times with a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 1029 from 1183 and we're left with 154.
Grab the next digit (9) from the dividend, add it to 154, then carry on: 1549 / 343

On to step 6:
When dividing 1549 by 343, we get 4 with a remainder of 177.
Use 4 as the next digit of our solution. 
Result so far: 434.0
Subtract 1372 from 1549 to get 177.
Take the next digit (4) from the dividend and append it to 177, then repeat: 1774 / 343

On to step 7:
1774 divided by 343 is 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 4345.0
If we subtract 1715 from 1774, we get 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 343

On to step 8:
The number 343 fits into 590 1 times, leaving a remainder of 247.
The next digit of our result is 1. 
Result so far: 43451.0
Subtracting 343 from 590 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 9:
2470 divided by 343 is 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 43451.7
The remainder is 69 after subtracting 2401 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
If we divide 690 by 343, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 43451.72
The remainder is 4 after subtracting 686 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
343 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 43451.72
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
If we divide 400 by 343, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 43451.7201
Subtracting 343 from 400 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 13:
343 can be fit into 570 1 times, resulting in a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 43451.72011
Deduct 343 from 570 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final result is 43451.72011 with a remainder of 0.000227.
