Catch divide-by-zero errors and introduce inline assembly
...
This commit updates the “Catching Exceptions” post to catch divide-by-zero errors instead of page faults. The reason is a subtle stack alignment bug, which is somehow caused by the additional error code on a page fault. This commit also adds a short introduction to inline assembly.

Catch divide error instead of page fault
...
The divide error pushes no error code. Thus we avoid stack misalignment (see #184 ).
