543239 divided by 2 
Let's see how many times 2 fits into 543239.

On to step 1:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 4 from 5.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Going ahead to step 2:
If we divide 14 by 2, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 14 away from 14, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Advancing to step 3:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
Subtracting 2 from 3 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

On to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2716.0
If we subtract 12 from 12, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 5:
3 divided by 2 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 27161.0
If we take 2 away from 3, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 6:
2 goes into 19 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 271619.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 271619.5
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 271619.5
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.

Let's proceed to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 271619.5
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.

After the division, we end up with 271619.5 and a remainder of 0.0.
