66015 octal to binary

Here we will show you how to convert the octal number 66015 to a binary number. First note that the octal number system has eight different digits (0 1 2 3 4 5 6 7) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 66015 from octal to binary are explained below.

Step 1)
Multiply the last digit in 66015 by 8⁰, multiply the second to last digit in 66015 by 8¹, multiply the third to last digit in 66015 by 8², multiply the fourth to last digit in 66015 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
1 × 8¹ = 8
0 × 8² = 0
6 × 8³ = 3072
6 × 8⁴ = 24576

Step 2)
Next, we add up all the products we got from Step 1, like this:

5 + 8 + 0 + 3072 + 24576 = 27661

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

27661 ÷ 2 = 13830 with 1 remainder
13830 ÷ 2 = 6915 with 0 remainder
6915 ÷ 2 = 3457 with 1 remainder
3457 ÷ 2 = 1728 with 1 remainder
1728 ÷ 2 = 864 with 0 remainder
864 ÷ 2 = 432 with 0 remainder
432 ÷ 2 = 216 with 0 remainder
216 ÷ 2 = 108 with 0 remainder
108 ÷ 2 = 54 with 0 remainder
54 ÷ 2 = 27 with 0 remainder
27 ÷ 2 = 13 with 1 remainder
13 ÷ 2 = 6 with 1 remainder
6 ÷ 2 = 3 with 0 remainder
3 ÷ 2 = 1 with 1 remainder
1 ÷ 2 = 0 with 1 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to 66015 octal to binary:

66015 octal = 110110000001101 binary
