Given two integers, dividend and divisor, return their division as a string in decimal format. If the fractional part is repeating, enclose the repeating sequence in parentheses. If the result is a finite decimal, return it as is. Negative values should be handled correctly. The divisor is guaranteed to be non-zero.
Example 1
Input: dividend = 7, divisor = 12
Output: 0.58(3)
Explanation: 7/12 = 0.583333..., so the repeating part is 3.
Example 2
Input: dividend = -10, divisor = 3
Output: -3.(3)
Explanation: -10/3 = -3.333..., so the repeating part is 3.
Example 3
Input: dividend = 0, divisor = 5
Output: 0
Explanation: 0 divided by any non-zero number is 0.
