Ways to tell them apart:
A long way is considered the standard and more grammatically correct form in both formal and informal writing.
A long ways is informal and more commonly heard in spoken language, often in American English.

Consider that ways sounds more plural and less precise when talking about distance.
Whenever in doubt, most style guides recommend sticking to a long way for clarity.
