We're dividing 339043 by 2 
Our goal is to divide 339043 by 2.

Step 1:
3 divided by 2 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 2:
If we divide 13 by 2, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 12 from 13 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 3:
2 goes into 19 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Moving on to step 4:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1695.0
If we subtract 10 from 10, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Advancing to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 16952.0
If we subtract 4 from 4, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Step 6:
3 divided by 2 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 169521.0
Deduct 2 from 3 and we're left 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.

Let's proceed to step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 169521.5
If we take 10 away from 10, 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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 169521.5
Deduct 0 from 0 and we're left 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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 169521.5
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.

The final outcome is 169521.5, with a leftover of 0.0.
