@brief Calculate the clock division with fractal part fast @note Speed first algorithm, Time complexity O(log n). About 8~10 times faster than the accurate algorithm

@param[in] clk_info The clock infomation @param[out] clk_div The clock division with integral and fractal part @return - 0: Failed to get the result because the division is out of range - others: The real output clock frequency
