404339 divided by 13 
We want to figure out the number of times 404339 can be divided by 13.

Moving on to step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 13

On to step 2:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 39 from 40 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 13

Moving on to step 3:
The number 13 fits into 14 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 31.0
If we take 13 away from 14, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 13

Advancing to step 4:
If we divide 13 by 13, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 311.0
Deduct 13 from 13 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 13

On to step 5:
3 divided by 13 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 3110.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 13

Let's proceed to step 6:
If we divide 39 by 13, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 31103.0
Subtract 39 from 39 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 7:
The number 13 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 31103.0
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.

Going ahead to step 8:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31103.0
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 31103.0, with a leftover of 0.0.
