It's a quick motion, but the essence is that while moving from the brake to the gas, you're also starting to apply the clutch to grab even at the still idle speed of the engine. It's not several steps but a fluid motion, and as weird as it sounds, it's something you pick up by feeling what the car needs to maintain the right engine speed while also not engaging the clutch too much and causing lugging or a stall. It's why most new manual drives start in a empty level place like a parking lot and practice just going from stop to moving slowly, over and over. I also told both my boys the first time they got behind the wheel the same thing my dad did - you WILL stall out the first time. And they did. :D But they both have and love driving stick now, and hate if they have to drive someone's automatic.
