How to convert 26 to binary, step by step
Keep dividing 26 by 2 and writing down each remainder. The remainders, read in reverse, are the answer.
| Number | ÷ 2 | Quotient | Remainder |
|---|---|---|---|
| 26 | 2 | 13 | 0 |
| 13 | 2 | 6 | 1 |
| 6 | 2 | 3 | 0 |
| 3 | 2 | 1 | 1 |
| 1 | 2 | 0 | 1 |
Reading the remainder column from the bottom up gives 11010, so 26₁₀ = 11010₂. Check it back: 16 + 8 + 2 = 26 — the 1 bits add up to 26.
In short: 26 ÷ 2 = 13 r 0 → 13 ÷ 2 = 6 r 1 → 6 ÷ 2 = 3 r 0 → 3 ÷ 2 = 1 r 1 → 1 ÷ 2 = 0 r 1 → read bottom-up: 11010₂
