In case of a page hit - the page's reference bit is set to one. 

The search for victim proceeds from the same place it stopped the
previous time. In your example, if the last time frame 2 was replaced,
the next time the second change algorithm starts selecting a victim
it proceeds from frame 3 (regardless of frame 8 page hit).
