The equivalence of an infinite series, such as (0.999… = 1) to a finite number is often not intuitively obvious to understand for most students. Yet, it is helpful to use an intuitive method to derive the equivalence that is familiar to most elementary school students. In this paper, a simple proof of the equality of 0.999… and 1 is provided by a non-traditional method using long division with an alternate quotient. This alternate method that uses long division to prove an infinite series of numbers can stimulate the imagination of students to use abstraction to understand the mathematical concept of infinity. This can be done without the use of geometric series.
