21132 octal to binary

Here we will show you how to convert the octal number 21132 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 21132 from octal to binary are explained below.

Step 1)
Multiply the last digit in 21132 by 8⁰, multiply the second to last digit in 21132 by 8¹, multiply the third to last digit in 21132 by 8², multiply the fourth to last digit in 21132 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
3 × 8¹ = 24
1 × 8² = 64
1 × 8³ = 512
2 × 8⁴ = 8192

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

2 + 24 + 64 + 512 + 8192 = 8794

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.

8794 ÷ 2 = 4397 with 0 remainder
4397 ÷ 2 = 2198 with 1 remainder
2198 ÷ 2 = 1099 with 0 remainder
1099 ÷ 2 = 549 with 1 remainder
549 ÷ 2 = 274 with 1 remainder
274 ÷ 2 = 137 with 0 remainder
137 ÷ 2 = 68 with 1 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 21132 octal to binary:

21132 octal = 10001001011010 binary
