Just enter the character you're interested and it'll list several sentences containing the character, I can't guarantee the quality though, I rarely use this service.

This is my go-to dictionary, for many characters it'll show you the stroke order and for many words it'll even show you example usage, though to be honest I've noticed that the example usage doesn't always align with the definition given.
