Fractions to Decimals

Write a program that will accept a fraction of the form N/D, where N
is the numerator and D is the denominator and print the decimal
representation. If the decimal representation has a repeating sequence
of digits, indicate the sequence by enclosing it in brackets. For
example, 1/3 = .33333333...is denoted as 0.(3), and 41/333 = 0.
123123123...is denoted as 0.(123). Use xxx.0 to denote an integer.
Typical conversions are:

1/3     =  0.(3)
22/5    =  4.4
1/7     =  0.(142857)
2/2     =  1.0
3/8     =  0.375
45/56   =  0.803(571428)

PROGRAM NAME: fracdec
INPUT FORMAT
A single line with two space separated integers, N and D, 1 <= N,D <=
100000.
SAMPLE INPUT (file fracdec.in)
45 56

OUTPUT FORMAT
The decimal expansion, as detailed above. If the expansion exceeds 76
characters in length, print it on multiple lines with 76 characters
per line.
SAMPLE OUTPUT (file fracdec.out)
0.803(571428)
