HOW TO CONVERT 12 TO BINARY
Method: divide by 2, collect remainders
12 ÷ 2 = 6 remainder 0
6 ÷ 2 = 3 remainder 0
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
Read remainders bottom to top: 1100
VERIFY: BINARY BACK TO DECIMAL
1×2^3 + 1×2^2 + 0×2^1 + 0×2^0
= 8 + 4 = 12 ✓
FUN FACT
12 is a highly composite number with 6 divisors. In binary, 12 = 1100 — top two bits set, bottom two bits zero. A clean split. In hex, 12 = C.

Divide 12 by 2 repeatedly, collecting remainders: 12 div 2 = 6 remainder 0 -> 6 div 2 = 3 remainder 0 -> 3 div 2 = 1 remainder 1 -> 1 div 2 = 0 remainder 1. Read remainders bottom to top: 1100.
Verify: 1*2^3 + 1*2^2 + 0*2^1 + 0*2^0 = 8 + 4 = 12. Each bit position represents a power of 2, starting at 2^0 = 1 on the right.
12 in other bases: octal = 14, hexadecimal = C. The binary form has 2 one(s) and 2 zero(s).
The bit pattern uses 4 bits and fits in 1 byte. When stored as a full byte: 00001100.
12 decimal to binary: 12 div 2 = 6 remainder 0 -> 6 div 2 = 3 remainder 0 -> 3 div 2 = 1 remainder 1 -> 1 div 2 = 0 remainder 1 -> read bottom to top: 1100. Verify: 1*2^3 + 1*2^2 + 0*2^1 + 0*2^0 = 12. Octal: 14, Hex: C.
