Well, darling, a reasonable estimate for 776 divided by 38 would be around 20.4. Just divide the nearest hundreds place numbers, and you'll get pretty close to the actual answer. But hey, who's counting anyway? Just remember, math is like a recipe - sometimes you can eyeball it and still come out with a decent result.
