If a bill passes the house of representatives , what is the next step in the process of a bill becoming a law ?

After passing the House, a bill needs to also move through the Senate approval process. This requires a vote to consider the bill, then next would be a committee to research it (if necessary), and then a Senate vote. All of this must be done and pass through both houses of Congress before a bill can go to the president's desk. 

The answer is because each slice has to be given equally to people.
