Using only positive digits, MILLY wrote down a two-digit number and a nine-digit number, both numbers being divisible by 14.
Splitting her nine-digit number into three three-digit numbers, she noticed that all three numbers were also divisible by 14.
Systematically replacing different digits by different letters, her two-digit number and nine-digit number ended up as MY VALENTINE.
