Playing with 64-tuples

Find the number of 64-tuples $(x_0, \dots, x_{63})$

such that $x_0, \dots, x_{63}$ are distinct elements of $\left\{1, 2, \dots, 2017 \right\}$ and

$x_0+x_1+2x_2+3x_3+\cdots+63x_{63}$

is divisible by $2017$

If your answer is of the form $n!\left(\displaystyle {m\choose n }- m\right)$

where $m,n$ are positive integers

submit $m-n$
