	\begin{align}
		Q &= \frac{N}{D} 
	\end{align}			
	\begin{itemize}
		\item $N$ and $D$ are arbitrary precision integers
	\end{itemize}
	\begin{align}
		N &= \sum_{i=0}^{S} d_i \beta^{i}
	\end{align}	
	\begin{itemize}
		\item $d_i$ are fixed size integers, $\beta = 2^{64}$
		\item Size $S$ grows as needed
		\item Operations are always exact
		\item Implemented by GNU Multiple Precision Library
	\end{itemize}
