Conquer the Divide - Faster Integer Division

Introduction

How to implement C-style integer division on a microcontroller that doesn't provide appropriate instructions? In school we learn how to divide long nunmbers [1]. Wikipedia tells us that we can do better in certain cases [2]. However, these algorithm are only better for numbers longer than a certain limit. For C operations they don't give any advantage. This article presents an algorithm based on piecewise polynomial approximation to implement this operation.

Stupid / Beginning Questions

I'm somewhat new to arduino and finally found out about libraries.  Unfortunately I have looked for instructions on how to create one and how to upload an existing library.  So if someone could give me step-by-step instructions on how to get this library i have here sitting on my desktop to something i can use in code. (please dummy-down the instructions).

It would also be helpful if someone could provide me with a small sample code for a robot that uses Ping)))
