Cut and Get Three First Number from ID

I am using Ruby on Rails. I have randomize ID for a model and I want to get the first three number from the ID and as "order code" save it to the DB.

My model consist of: id, first_name, last_name, and order_code.

For instance, the ID is 901233 then I want to put the 901 to the order_code. How to achieve that?

Thank you in advanced.
