| Number | ÷ 2 | Quotient | Remainder |
|---|---|---|---|
| 46 | 2 | 23 | 0 |
| 23 | 2 | 11 | 1 |
| 11 | 2 | 5 | 1 |
| 5 | 2 | 2 | 1 |

Reading the remainder column from the bottom up gives 101110, so 46₁₀ = 101110₂. Check it back: 32 + 8 + 4 + 2 = 46 — the 1 bits add up to 46.
In short: 46 ÷ 2 = 23 r 0 → 23 ÷ 2 = 11 r 1 → 11 ÷ 2 = 5 r 1 → 5 ÷ 2 = 2 r 1 → 2 ÷ 2 = 1 r 0 → 1 ÷ 2 = 0 r 1 → read bottom-up: 101110₂
