When you scan, you can do so using Optical Character Recognition (OCR). It's an imperfect science, so it will have it's faults. But, try and scan them to an editable document, then finish the edits on your own. (This is done outside of HubPages, they don't have anything remotely close to this ability.)
On they're in a digital form, you can copy and paste to your heart's content. Unless your objective is to show them in the original hand-written form, then the answer is to scan them to a picture, and then upload the picture.
