You write it 4,300,500.22 because the 4 goes in the million's place, the 3 goes in the hundred thousand's place, the 5 goes in the hundred's place, the first 2 goes in the tenth's place, and the last 2 goes in the hundredth's place.

You can write that as you wrote in the question: "4.76 million". This would be pronounced as "4 point seven six million". You can also write it as "4 million, seven-hundred and sixty thousand".
