long to int conversion in java not working

I am working on a problem with big number's in java.

int temp =0;
long last = 218212982912L;
temp = (int) last%10;
last = last/10;

for the above line of code I get the 

temp = -4

in the first iteration. I am not sure what is the problem. I have tried a lot of solution online available.

The last positive you can get is 2,147,483,647 and when you are explicitly converting a larger number to int, your will get unpleasant results but if you put extra parentheses like (int) (someLong % 10), first the long operation get executed (which results in smaller long value that fits int memory space) and then you can cast it to int without worry

Put parentheses around last%10

The cast to int is being applied before the modulus operation
