Your article isn't massively long I'd say maybe split it into 3 or 4 parts depending how it fits into your site design.
To embed images and tables within the body of the text you can use the float style property to align them to the left or right. You can also look at clear, margin and padding to improve the placement.
for example you can float an image within text as follows
<img src="/images/picture.gif" alt="my picture" style="float:right; margin-left:10px;">
