Date & time with a flow. The Flow is usually zero.

I need to count the zeros from the first zero up to and including the next non-zero number, then divide the non-zero number and populate the adjacent column with the average flow number since the last non-zero. i.e. there are 18 zeros until 13350, 13 zeros until 8640, Like this:

4/1/2013 0:00      0      
4/1/2013 0:01      6590      
4/1/2013 0:02      0      741.6666667
4/1/2013 0:03      0      741.6666667
