The div on the inside is floated to the left. This makes that whole div outside the border of the containing div. If I take the "float: left" property away from it, then that entire div will be inside the containing divs borders. Why is this so, and what can I do to make the inside div inside the borders of the containing div, while keeping its float property.

divs are block elements, so they take up as much space as the can. Unbounded, the div will fill its entire container. To get the div where you want it, try

<div style="position: relative;">
<div <style="position: absolute; left: 0px;">
</div>
</div>

Just provide wrapper's or tubes inside your floated div to preserved the whole layout.
Try this one:

maindiv should expand dynamically based on the content of this - 
div and it should fully enclose this div.</p>

Divs do NOT always expand to fill their containers. This is a known bug in the definition of div.

They seem to work correctly if nothing but text is present, but if you put a div inside something else (especially a table cell), or if you put something else (such as an image, or a bunch of br tags) inside the div, then strange things happen. The div shrinks smaller than its container, or expands beyond the bounds of its container. Different browsers often behave in different ways in these cases.
