We look at the division of 512926 by 2 
Let's see how many times 2 fits into 512926.

Advancing to step 1:
2 goes into 5 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

On to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 10 from 11 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Let's proceed to step 3:
2 goes into 12 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 256.0
The remainder is 0 after subtracting 12 from 12.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Let's proceed to step 4:
2 goes into 9 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2564.0
The remainder is 1 after subtracting 8 from 9.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

Moving on to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 25646.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

On to step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 256463.0
Subtracting 6 from 6 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.

Moving on to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 256463.0
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 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 256463.0
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.

The final result is 256463.0 with a remainder of 0.0.
