1. Does fat "dissolve" and the body gets rid of it through normal functions?
2. How does diet and exercise stop the formation of more fat?
3. Why does diet and exercise get rid of existing fat and how?
Where does the fat go?

Re: Where does the fat go?
The body can manipulate Fat levels through differing hormones and also things like thermogenic activity and the need to use fat as a secondary energy source when carbohydrate energy is depleted.
There are certain substances namely Leptin, Ghrelin and Adiponectin, that influence Fat.
Ghrelin actually has a negative effect on Fat stores and tends to be produed more when your not sated.
The other two are produced by Fat cells to regulate Fat to some extent, with Leptin having the potential to be less effective if you're overweight, as it's effects may have been nullified to some extent, by the persons body developing resistance to it.
The body can also burn white Fat via the use of "Brown Fat". Until recently Brown was thought to exist in babies, but dissapear by adulthood, then last year, swedish scientists discovered it does exist in reasonable levels in adults.
It contain Mitochondria, the things that store ATP energy in muscles that helps make muscles move. As yet though science cannot isolate any specific ways to triggger it off so it could do this.
Diet can get rid of Fat, by to some extent cutting the caloric intake required, which means you get less excess calories that will convert to Fat. You can also intake Fats that have a much lower or no propensity to store, thus preventing the body from maintaining fat levels that way too.
Exercise creates a thermogenic environment which burns calories.
Cooking fat can reduce Fat content, so it's like this thermogenic elevation could also to some extent burn Fat, because some Fat would be reduced by increased heat exposure. This last sentence is me hypothesising, not speaking from an educated standpoint.
Plus exercise can recruit Fat for energy, when carbs are at a deficeit as mentionee earlier.
Danish scientists a few years ago, also managed to test people with Calcium based diets.
Low calcium diet for a week, with stool collection. Next week high Calcium diet with stool collection, which resulted in more excreted Fat, but the way in which this happened in vivo I'm not sure of, as I'm not very sure how Calcium has a relationship with Fat, but it seems as if Calcium binds to Fat and has some kind of preventative effect, relating to the bodies ability to metaboilise it, so it gets channelled out as I understand it.
However there is controversy surrounding very high Calcium intake, not least as high Calcium can interfere with Iron uptake, but it's reckoned high Calcium can cause Osteoperosis as much as low Calcium, because the Osteoblasts that upload Calcium to Bones, get overworked and end up with a reduced ability in later life to function properly, causing to lowered Calcium uptake and eventually Osteoperosis. A high intake being around 2,000mg's a day as opposed to 1,000-1,200mg's a day, (RDA).
That's the theory anyway.
Plus too much Calcium can cause Calcification, which may result in a stiffening of the blood pathways.
I digress a little though.
Fat is also broken down by things like B Vitamins and also Bile, which is produced in the Liver, stored in the Gall Bladder and dispensed into the Duodenum, the vertical tract directly below the Pyloric Valve at the base of the Stomach.
Some people can also get something called Whipples Disease, (caused by something called Tropherima Whippelli, (not sure if I've spelled that correctly). That can be bad as it prevents Carbs and Fats being metabolised properly.
You can taker o rleave this next bit, as it's a littl off track from what you asked, but whilst I'm not 100% certain how Fat is oxidated out of the body, (there was something posted here a while back), it can cause things like Atheromas, which are fatty blockages in the blood pathways, Periphery Arterial and Venerial disease, where you get blockages in the Legs, Lipomas which are little benign fatty Tumours and even contribute to strokes, if you get a Fat blockage in the Brain, or a piece of a blood clot detaches and collects some fat, before lodging elsewhere, (an Embolism), a static clot is a Thrombus.
The blockage is a Cerebrovascular Infarction, as opposed to a Cerebrovascular Hemorrhage which is a rupturing, as I understand it.
The other problem Fat casues is Viscerol Fat which collects around the Organs causing issues, or I supposed potential pressure and strain on them.
There may be other things Fat can contribute too, but I've probably embellished a little on what you asked. Apologies if some of that looks a little baffling.
