How to remove inner div from create block in drupal 7
The markup you require removing comes from one or more template files. While i have no idea what theme you are using, ill assume its one that hasn't overidden the default template files..

If you go and get the file modules/system/region.tpl.php and copy it to your theme folder you can remove the markup you do not require. e.g. delete &lt;div class="region region-footer-bottom-right"&gt;

To get rid of the rest of the markup you will have to override the block template in the same fashion, to only remove the markup from 1 specific block you can use naming suggestions here https://www.drupal.org/node/1089656

note: Flush the caches for the theme to pick up the presence of any new template files.
