DIV is used for many things, but for this, it is used to call a CSS class you have pre-set in your style settings. So putting something like <div class="postbit"> calls the CSS options for 'postbit'

You'd put the DIV code (as skinvb has posted above) in your postbit template. You'd put the code around each of the variables which call something like Join Date, or posts etc. placing the variable inbetween the code.
