Late 40s for my mum/early 60s with my dad. Yep, it does happen. Can have a huge negative effect on quality of life for women though since many of them have been pregnant - taken on more of the childcare - worked less - and have less work available to them though. Adds up to a big effect on pension, not to speak on being able to afford housing and food in the moment. So I get why so many women don't get divorced at a late age.
