How to convert 6 to binary, step by step
Keep dividing 6 by 2 and writing down each remainder. The remainders, read in reverse, are the answer.
| Number | ÷ 2 | Quotient | Remainder |
|---|---|---|---|
| 6 | 2 | 3 | 0 |
| 3 | 2 | 1 | 1 |
| 1 | 2 | 0 | 1 |
Reading the remainder column from the bottom up gives 110, so 6₁₀ = 110₂. Check it back: 4 + 2 = 6 — the 1 bits add up to 6.
In short: 6 ÷ 2 = 3 r 0 → 3 ÷ 2 = 1 r 1 → 1 ÷ 2 = 0 r 1 → read bottom-up: 110₂
