The outer end of a step has broken off. See first photo.

I'd probably replace the whole slab, but it continues under the steps
above and supports them. See second photo.

Is there a way of repairing this that won't just crumble away fairly
quickly? The slabs have a small overhang at the front.

These steps are in constant use, so I need a repair that can be done
quite quickly, without stopping people using the steps completely.
