How to divide a number by 2

When I divided a large number by 2 , doing the division on paper, It took me some time before I got the final answer . As I studied each number, I found out that the number can be divided by 2 using this method. Note this one:

4534685734 / 2

The rule is simple.
1. Simply get one-half of each number. If the number is odd, half of that number carries a fraction 1/2. But write only the whole number on the quotient.
Add 10 to the next number on the dividend and get one half of it.

             4 5 3 4 6 8
--------------------------- = 2 2 6 7 3 4
                     2

1/2 of 4 is 2
1/2 of 5 is 2 1/2; write 2 as quotient and add 10 to the next number, 3 ; 3 becomes 13
1/2 if 13 is 6 1/2, write 6 as quotient and add 10 to the next number, 4 ; 4 becomes 14
1/2 of 14 is 7
1/2 of 6 is 3
1/2 of 8 is 4

The answer is 2 2 6 7 3 4
