how to configure .htaccess to such that I can have access to subfolders and subdomains in a Laravel project

I currently build most of my apps with Laravel 5.1 and host them on share hosting. The major challenge I have come across is that I cannot have access to sub folders e.g. http://ift.tt/1DpxEGu, also when I try to access a sub-domain for example admins.mydomain, I keep having Internal server error(error 500).
I need help to get over this, thanks.
