How do I keep my puppy from pooping in her crate?

I bought a puppy from the Shamrock Foundation about 2 months ago (she is 5 months old now). I feed her in the evening and she sleeps with me at night. She stays in bed with me the entire night and I take her out in the morning first thing. She pees 3 or 4 times and poops every time and I reward her with a small treat. Unfortunately, I have to put her in a wire crate when I leave for work at 7 and isnt let out until I get home around 4. To my knowledge, she doesn't whine or cry anymore but she does pee and poop multiple times in the crate. She will then lay in it and I have to bathe her and clean the crate every day. The crate came with a divider to make the area smaller, which I tried but that didn't work. So, I took the divider out thinking maybe she would go in one place and sleep on the other end and that didn't work. So then I tried locking her in the laundry room with a puppy pad. She went on the puppy pad, but tore up the linoleum floor and scratched the paint off the door. I know she can hold it long enough because she does it every night. Any tips on how to keep her from going in her crate every day? This has been going on for the last couple months. I am hoping it is something she will grow out of, but I want to promote good behavior from her.
