You can't.
Jet is an embedded database technology. The database engine runs in-process and needs full file I/O access to the MDB, LDB, and MDW files involved.
There is the possibility of using Remote Data Service but this is an "unconnected" model of access, basically a sort of Web Service. A 3rd party hosting provider would be very unlikely to provision this service or give you the ability to yourself.
Instead you'll probably have to design and implement some sort of Web Service or otherwise run a middle tier on the server instead.
