Java实现：

```class Solution {
public int divide(int dividend, int divisor) {
int res=0;
if(divisor==0){
return Integer.MAX_VALUE;
}
if(dividend==Integer.MIN_VALUE&&divisor==-1){
return Integer.MAX_VALUE;
}
long m=Math.abs((long)dividend);
long n=Math.abs((long)divisor);
while(m>=n){
long t=n,p=1;
while(m>=(t<<1)){
t<<=1;
p<<=1;
}
res+=p;
m-=t;
}
if((dividend>0 && divisor>0)||(dividend<0 && divisor<0)){
return res;
}else{
return -res;
}
}
}
```
