When something is described as 'utterly' done, it means it's complete and total—absolutely no doubt about it. It's like saying something is 100% done. Think of it as the ultimate degree of something. It leaves no room for partialness or doubt. It's stronger than 'very' or 'really'. Imagine crushing a soda can completely flat; it's utterly crushed. Or finishing a video game and beating the final boss; you've utterly conquered it.
