长整数除法规则：

例 123456 除以 7，求商和余数
规则：
初始化tempRemainder = 0，
从被除数的最高位开始，由tempRemainder*10 + nums[index]构成一个二位数

tempRemainder*10+nums[top] = 01，01除以7  得商=0，tempRemainder=1
tempRemainder*10 + nums[top-1] = 12，12除以7  得商=1，tempRemainder=5
tempRemainder*10 + nums[top-2] = 53, 53除以7 得商=7，tempRemainder=4
以此类推
最后一轮的tempRemainder即为长整数除法的最终余数，总结果的商为 017636（每轮除得结果的商进行移位再相加或字符串拼接）
