If all 435 members of the House of Representatives votes, then at least 290 must vote to override. If all 100 Senate members vote, then at least 67 must vote for the veto. A two-thirds vote is technically considered a supermajority, which is much more difficult to get than a traditional simple majority. Fewer than 10 percent of all presidential vetoes have been overridden by a vote in the chambers of Congress.
If it is vetoed by the president, it is sent back to the house in which it originated. In order to override the veto, it is much more difficult for congress. They need to obtain a two thirds majority in each house for the veto to be overridden. Because in more cases than not, the bill did not pass with this high of a majority, it is very difficult for the veto to be overridden. Until recently the average override was 1 of every 18 vetoes.
