How to convert 32 to binary, step by step
Keep dividing 32 by 2 and writing down each remainder. The remainders, read in reverse, are the answer.
| Number | ÷ 2 | Quotient | Remainder |
|---|---|---|---|
| 32 | 2 | 16 | 0 |
| 16 | 2 | 8 | 0 |
| 8 | 2 | 4 | 0 |
| 4 | 2 | 2 | 0 |
| 2 | 2 | 1 | 0 |
| 1 | 2 | 0 | 1 |
Reading the remainder column from the bottom up gives 100000, so 32₁₀ = 100000₂. Check it back: 32 = 32 — the 1 bits add up to 32.
In short: 32 ÷ 2 = 16 r 0 → 16 ÷ 2 = 8 r 0 → 8 ÷ 2 = 4 r 0 → 4 ÷ 2 = 2 r 0 → 2 ÷ 2 = 1 r 0 → 1 ÷ 2 = 0 r 1 → read bottom-up: 100000₂
