Fractions to Decimals

Write a program that will accept a fraction of the form $\frac{N}{D}$, where $N$ is the numerator and $D$ is the denominator, that prints out the decimal representation. If the decimal representation has a repeating sequence of digits, it should be indicated by enclosing it in brackets. For example, $\frac{1}{3}=.33333333...$is denoted as $.(3)$, and $\frac{41}{333}=.123123123...$ is denoted as $.(123)$.

Typical conversions are:

$\frac{1}{3}=.(3)$
$\frac{22}{5}=4.4$
$\frac{1}{7}=.(142857)$
$\frac{3}{8}=.375$
$\frac{45}{56}=.803(571428)$

Sample Run

ENTER $N,D:1,7$

$\frac{1}{7}=.(142857)$

What is the answer for the fraction $\frac{11}{59}$?
