42066 octal to binary

Here we will show you how to convert the octal number 42066 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 42066 from octal to binary are explained below.

Step 1)
Multiply the last digit in 42066 by 8⁰, multiply the second to last digit in 42066 by 8¹, multiply the third to last digit in 42066 by 8², multiply the fourth to last digit in 42066 by 8³, and so on, until all the digits are used:

6 × 8⁰ = 6
6 × 8¹ = 48
0 × 8² = 0
2 × 8³ = 1024
4 × 8⁴ = 16384

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

6 + 48 + 0 + 1024 + 16384 = 17462

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.

17462 ÷ 2 = 8731 with 0 remainder
8731 ÷ 2 = 4365 with 1 remainder
4365 ÷ 2 = 2182 with 1 remainder
2182 ÷ 2 = 1091 with 0 remainder
1091 ÷ 2 = 545 with 1 remainder
545 ÷ 2 = 272 with 1 remainder
272 ÷ 2 = 136 with 0 remainder
136 ÷ 2 = 68 with 0 remainder
68 ÷ 2 = 34 with 0 remainder
34 ÷ 2 = 17 with 0 remainder
17 ÷ 2 = 8 with 1 remainder
8 ÷ 2 = 4 with 0 remainder
4 ÷ 2 = 2 with 0 remainder
2 ÷ 2 = 1 with 0 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 42066 octal to binary:

42066 octal = 100010000110110 binary
