We divide 516912 by 2
We want to divide 516912 by 2.

Advancing to step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 4 away from 5, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 2:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 1 after subtracting 10 from 11.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Advancing to step 3:
16 divided by 2 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
Subtract 16 from 16 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 4:
If we divide 9 by 2, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 2584.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Advancing to step 5:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 25845.0
Deduct 10 from 11 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Moving on to step 6:
2 goes into 12 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 258456.0
Subtract 12 from 12 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.

Let's proceed to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 258456.0
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.

Step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 258456.0
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.

In conclusion, the division gives 258456.0 with a balance of 0.0.
