Indicate the Instance of Consecutive Zeros in a Row

Hello,

I am trying to figure out a formula where an indicator of 1 is put at the end of a row that contains an instance of seven consecutive zeros in that same row. Also the number of times there are seven consecutive zeros does not matter, if there is one instance then add a 1 indicator, if there are 5 instances then a 1 indicator is still fine.

So in the sample I have attached, rows 3 and 6 would receive a 1 indicator, and the rest would receive nothing or a 0 is fine as well.

Thanks for any help.

EDIT: I have this so far. This is a modified version of a formula I found else where on the forum that pretty much works for what I'm trying to accomplish.

=SUMPRODUCT(--(COUNTIF(OFFSET(A6,0,ROW(INDIRECT("1:"&MATCH(9.99999999999999E+307,A6:V6)-6))-1,1,7),0)=7))

However, I'm not 100% such exactly what its doing, so an explanation would be great
