Default Problem

Determine all the 5-digit numbers that when the first digit and last digit are taken away, the new number is 2/215 of the original?
abcde is the number,
So 2(10000a+1000b+100c+10d+e)=215(100b+10c+d)

So... yeah...help!

Does it have to be an integer?
If not, than there's an infinite number, so I'm guessing it has to be.
