22211 octal to binary

Here we will show you how to convert the octal number 22211 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 22211 from octal to binary are explained below.

Step 1)
Multiply the last digit in 22211 by 8⁰, multiply the second to last digit in 22211 by 8¹, multiply the third to last digit in 22211 by 8², multiply the fourth to last digit in 22211 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
1 × 8¹ = 8
2 × 8² = 128
2 × 8³ = 1024
2 × 8⁴ = 8192

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

1 + 8 + 128 + 1024 + 8192 = 9353

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.

9353 ÷ 2 = 4676 with 1 remainder
4676 ÷ 2 = 2338 with 0 remainder
2338 ÷ 2 = 1169 with 0 remainder
1169 ÷ 2 = 584 with 1 remainder
584 ÷ 2 = 292 with 0 remainder
292 ÷ 2 = 146 with 0 remainder
146 ÷ 2 = 73 with 0 remainder
73 ÷ 2 = 36 with 1 remainder
36 ÷ 2 = 18 with 0 remainder
18 ÷ 2 = 9 with 0 remainder
9 ÷ 2 = 4 with 1 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 22211 octal to binary:

22211 octal = 10010010001001 binary
