407939 ÷ 14 
We're looking to find how many times 14 goes into 407939.

Going ahead to step 1:
14 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 14

Step 2:
40 divided by 14 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 28 from 40 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 14

Advancing to step 3:
127 divided by 14 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 126 from 127 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 14

On to step 4:
If we divide 19 by 14, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 291.0
If we subtract 14 from 19, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 14

Step 5:
When dividing 53 by 14, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2913.0
Subtract 42 from 53 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 14

On to step 6:
119 divided by 14 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 29138.0
If we subtract 112 from 119, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 14 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 29138.5
If we subtract 70 from 70, 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.

On to step 8:
When dividing 0 by 14, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29138.5
If we take 0 away from 0, we end up with 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 9:
14 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29138.5
Subtracting 0 from 0 leaves us with 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 29138.5, with a leftover of 0.0.
