Split Word Docm

I have a 208 page word document (docm) that I need to split into 104 sperate documents.
I have tried several example macors that I found on the internet, including one's which contain delimiters, etc.
However, none seem to work.

Each page contains headers and footers so I cannot use cut and paste.
Also, each page is landscape so I need when using document.add I would need to change the orientation to landscape and also the margins to narrow.

Can anyone provide me with pointers on how to do this?

I would have posted my progress so far on here but I haven't made any!

Thank you.

Sorry.
Yes it should.
I have closed this one and added it to the word forum.
