Yes, well definitely a comedy at any rate. I dunno if they are necessarily every day situations. 

Is the character the "star" of the show?

No

Clues so far:

Name starts with D
Not a cartoon
Comedy
From the 80s and 90s
Sitcom but the everyday situation are unique to their situation and are not normal situations
The character is the star of the show
The character's name is not in the title of the show

Bonus Clue:

The show was continued as a revival in the 2000s.

 

Hmm... a show that aired in the 80s and 90s, and continued as a revival in the 2000s, and it's a male character that starts with a D.

Hmm... Derek Wheeler from Degrassi High?
