Hi Richzrd1, all you have to do put a split in the timeline at the spot you want to paste the clip, or if you already have a break at that point just paste in there.
The easiest way I have found to get the marker right at the start of a clip is click on the clip, choose preview "clip" not "movie" then hit the stop button. This moves the marker right to the beginning of the clip.
I hope I have explained that properly.
Cheers
