1. Determine if your decimal number is 0 or 1. If it is either of these numbers, the binary number is the same as the decimal number. If it is not either of these numbers, move on to Step 2.
2. Find the largest possible power of 2 that can be subtracted from the decimal number without making it negative. Then, subtract it.
3. Write a "1" as the first digit of your binary number.
4. Decide whether you can subtract the next smallest power of 2 from what is left of the decimal number without making it negative.
5. Deduct this power of 2 from the decimal number and write "1" as the next digit of your binary number if your results were positive for Step 5. If they were negative, write "0" as the next digit of your binary number.
6. Repeat Step 5 and 6 until you reach the number 0. The numbers you write down during this process are the binary number.
