how bitwise shift operation is happening ?

I have done a small program to understand, how bitwise left shift operation is working ? 

var result = 2088883663 << 5;
Binary value for 2088883663 is 01111100100000011101010111001111
result binary value is 10010000001110101011100111100000 => my expected result should be 2419767776 
but it overflows with int MaxValue so I thought result would be less than expected result (2419767776)
but I got 
Output:

-1875199520 (negative value) I don't know how it is working can any one guide me ?

NOTE: I know for positive numbers, shifting operation makes 0(zero) to fill backing element.
