I made several changes to your code:

One of the errors with your code is the array that is initialized to have 0 integers. I simply initialized the array to 32. Another modification I made was to print out the array using a for loop, from the largest to smallest index. This way the most-significant bit is on the left.

Other than that your algorithm for converting to binary works fine.
