The last three digits of a number is $76x36$ is $x36$ which is divisible by $8$ , where $x$ is the smallest digit.

when $x=1$ the last three digit of $76x36$ is $136$ which is also divisible by $8.$

Hence, the smallest digit to be placed in blank space $=1$ then digit $1$ to make $76.....36$ divisible by $8$.
