323439 ÷ 13 
Let's see how many times 13 fits into 323439.

Step 1:
When dividing 3 by 13, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 13

Step 2:
13 can be fit into 32 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 26 from 32 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 13

Step 3:
63 divided by 13 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 52 away from 63, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 13

On to step 4:
If we divide 114 by 13, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 248.0
If we take 104 away from 114, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 13

On to step 5:
If we divide 103 by 13, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2487.0
Subtract 91 from 103 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 13

Let's proceed to step 6:
129 divided by 13 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 24879.0
Deduct 117 from 129 and we're left 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.

Let's proceed to step 7:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 24879.9
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 24879.92
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 24879.923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 24879.923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 13, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 24879.92307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
If we divide 90 by 13, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 24879.923076
Deduct 78 from 90 and we're left 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.

Going ahead to step 13:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 24879.9230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 24879.92307692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 24879.92307692, and the remainder is 4e-09.
