We say a non-negative integer  $n$  "*contains*" another non-negative integer  $m$ , if the digits of its decimal expansion appear consecutively in the decimal expansion of  $n$ . For example,  $2016$  *contains*  $2$ ,  $0$ ,  $1$ ,  $6$ ,  $20$ ,  $16$ ,  $201$ , and  $2016$ . Find the largest integer  $n$  that does not *contain* a multiple of  $7$ .
