SQL & PL/SQL

Below you will find my table DDL, inserts and query. I'm simply trying to calculate a percentage based on my_budget over total_budget. For all intents and purpose total budget is a static amount so it will not differentiate from row to row.The issue however is that in certain situations it appears that the total percent calculation is greater than 100%. If you look at my results I end up with 100.01. Can someone give me a pointer how to prevent that from happening. I feel like I'm missing something simple on this one. I really don't care where the -.01 gets reduced from my percent calculation to get an even 100%.
