21532 octal to binary

Here we will show you how to convert the octal number 21532 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 21532 from octal to binary are explained below.

Step 1)
Multiply the last digit in 21532 by 8⁰, multiply the second to last digit in 21532 by 8¹, multiply the third to last digit in 21532 by 8², multiply the fourth to last digit in 21532 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
3 × 8¹ = 24
5 × 8² = 320
1 × 8³ = 512
2 × 8⁴ = 8192

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

2 + 24 + 320 + 512 + 8192 = 9050

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.

9050 ÷ 2 = 4525 with 0 remainder
4525 ÷ 2 = 2262 with 1 remainder
2262 ÷ 2 = 1131 with 0 remainder
1131 ÷ 2 = 565 with 1 remainder
565 ÷ 2 = 282 with 1 remainder
282 ÷ 2 = 141 with 0 remainder
141 ÷ 2 = 70 with 1 remainder
70 ÷ 2 = 35 with 0 remainder
35 ÷ 2 = 17 with 1 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 21532 octal to binary:

21532 octal = 10001101011010 binary
