WebMay 5, 2010 · Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit. WebJan 24, 2024 · Bits that are shifted off the end of the binary number are lost forever. The bitwise right shift (>>) operator shifts bits to the right. 1100 >> 1 is 0110. 1100 >> 2 is 0011. 1100 >> 3 is 0001. Note that in the third case we shifted a bit off the right end of the number, so it is lost. havilah seguros
