After going over the numbers I believe it was a lazy copy/paste job.
Note for 31 Dec 2012 $66,186
Note for 31 Mar 2013 $51,334
Legal Fees for default on the note $5000
Conversion of the note $19,852 and $1,205 interest(I guess that is included in the conversion or the math doesn't make sense).
$66,186
-$19852
$46334
+$5000
$51334
In other words it took 11,835,000 shares to lower the note by $14,852
