以下是一种解决方法，使用循环和减法来实现除法操作：

def divide(dividend, divisor):
    if divisor == 0:
        raise ZeroDivisionError("除数不能为0")

    # 处理特殊情况
    if dividend == 0:
        return 0
    if divisor == 1:
        return dividend
    
    # 确定结果的符号
    negative = (dividend < 0 and divisor > 0) or (dividend > 0 and divisor < 0)
    
    # 将被除数和除数都转换为正数
    dividend = abs(dividend)
    divisor = abs(divisor)
    
    quotient = 0  # 商
    while dividend >= divisor:
        dividend -= divisor
        quotient += 1

    # 根据符号确定最终的结果
    if negative:
        quotient = -quotient
    
    return quotient

示例用法：

print(divide(10, 3))  # 输出: 3
print(divide(7, -2))  # 输出: -3
print(divide(0, 5))   # 输出: 0
print(divide(8, 0))   # 抛出异常: ZeroDivisionError: 除数不能为0
