439489 ÷ 13 
We're looking to find how many times 13 goes into 439489.

Let's proceed to step 1:
The number 13 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 13

Step 2:
The number 13 fits into 43 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 39 from 43, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 13

Moving on to step 3:
49 divided by 13 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 39 away from 49, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 13

Let's proceed to step 4:
When dividing 104 by 13, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 338.0
If we subtract 104 from 104, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 13

Moving on to step 5:
If we divide 8 by 13, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 3380.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 13

Going ahead to step 6:
The number 13 fits into 89 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 33806.0
Deduct 78 from 89 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
13 goes into 110 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 33806.8
If we subtract 104 from 110, we 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.

Going ahead to step 8:
When dividing 60 by 13, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 33806.84
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 13 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 33806.846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 13, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 33806.8461
Subtract 13 from 20 to 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 11:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33806.84615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
50 divided by 13 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 33806.846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 33806.8461538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
13 goes into 60 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 33806.84615384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 33806.84615384 with a balance of 8e-09.
