不使用’/’运算符的除法

给定两个数字，不使用’/’运算符将其除以一个。
例子 ：

Input : num1 = 13, num2 = 2
Output : 6

Input : num1 = 14, num2 = -2
Output : -7

Input : num1 = -11, num2 = 3
Output : -3

Input : num1 = 10, num2 = 10
Output : 1

Input : num1 = -6, num2 = -2
Output : 3

Input : num1 = 0, num2 = 5
Output : 0

为了执行除法运算而不使用’/’运算符，我们采用了这种方法，在该方法中，我们计算从num1减去num2的成功次数或完成次数。其中num1是要除的数字，num2是我们必须除以num1的数字。
