$ sudo apt-get install libc6-i386

I've found that for the 32 apps I run, that's all I need.  If the
application still does not run, then use the utility "ldd" on the binary.
It will list the libraries it needs (you must have the above one installed
first) and you can install those by hand.

If there's a better way to do it using multiarch, then I'd encourage doing
that instead.
