If you've gotten up what you can see, that's a very good start. To get the very small pieces, do a sweeping pattern with a damp sponge. Press it firmly on the flooring and pull inward and advance onward, working youself slowly to the center. Use duct tape wrapped around your hand, sticky-side out, to collect the fine scatterings left in your circle's center. Careful with the sponge. Put it and the tape in a ziplock and dispose of it properly. To make yourself feel even better, the duct tape trick works well on something like a Swiffer pad. Wrap it around the base sticky-side out and tamp it in a pattern to cover the entire floor. Change tape as needed.
