Divide 3 by 2 repeatedly, collecting remainders: 3 div 2 = 1 remainder 1 -> 1 div 2 = 0 remainder 1. Read remainders bottom to top: 11.
Verify: 1*2^1 + 1*2^0 = 2 + 1 = 3. Each bit position represents a power of 2, starting at 2^0 = 1 on the right.
3 in other bases: octal = 3, hexadecimal = 3. The binary form has 2 one(s) and 0 zero(s).
The bit pattern uses 2 bits and fits in 1 byte. When stored as a full byte: 00000011.
3 decimal to binary: 3 div 2 = 1 remainder 1 -> 1 div 2 = 0 remainder 1 -> read bottom to top: 11. Verify: 1*2^1 + 1*2^0 = 3. Octal: 3, Hex: 3.
