I want to countif consecutive two cells have "SAY value" 0

So first 4 columns will return frequency function =2

if all columns given as cell range for formula, then frequency should be = 3

as at end only 3 columns have two consecutive zero cell.

How can i write formula. I tried if and array but making mistake.
