A 73mb html file would indicate that you are doing things so incredibly wrong, or incredibly different, that NO ONE can help you without knowing more about it.
And the gomers here who have tried (by suggesting things as hilarious as word...) just go to show you of how little use the answers that try will be.
Seriously, I have no clue what you are doing to accomplish such a thing...but it isn't right. God help the internet if you put that thing into production.
Just to give you an idea of why I'm being so blunt: I would say most of this to someone who said their web page was 5 freakin mb. Yours...well, yours is 15 times that. I'm astounded that you've gotten this far...
The only exception is if you are doing something VERY different from what we call "web design"...like, you're creating a page to launch a space shuttle from or something.
