About 5 a week here, two a day on a few occasions because of diarrhea from swallowing a ton of snot (ewwww). If she's going that regularly, any chance you can tell before she goes and that she'd be willing to sit on a potty and have you sing songs or something while she goes? Even if you just had it work once, it'd help reduce your poopy diapers.
Also, if the poopy diapers regularly happen within 5-15 minutes of each other, I'd definitely hold her over a toilet or sit her on a potty after taking off the first poopy diaper (and wiping her down). When my 16 month old poops, she'll pause for a bit before bearing down again and pooping more.
On days when she has a poop, it's frequently more like 3-4 poops.
Oh, and I switched to watered down juice after a couple days with multiple huge poops. So do consider diet if there's a ton of pooping. For us, it wasn't a normal thing so it was important to change how we were handling juice (which had been my "lazy snack" now I cook an egg instead.

)
