30440 octal to binary

Here we will show you how to convert the octal number 30440 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 30440 from octal to binary are explained below.

Step 1)
Multiply the last digit in 30440 by 8⁰, multiply the second to last digit in 30440 by 8¹, multiply the third to last digit in 30440 by 8², multiply the fourth to last digit in 30440 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
4 × 8¹ = 32
4 × 8² = 256
0 × 8³ = 0
3 × 8⁴ = 12288

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

0 + 32 + 256 + 0 + 12288 = 12576

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.

12576 ÷ 2 = 6288 with 0 remainder
6288 ÷ 2 = 3144 with 0 remainder
3144 ÷ 2 = 1572 with 0 remainder
1572 ÷ 2 = 786 with 0 remainder
786 ÷ 2 = 393 with 0 remainder
393 ÷ 2 = 196 with 1 remainder
196 ÷ 2 = 98 with 0 remainder
98 ÷ 2 = 49 with 0 remainder
49 ÷ 2 = 24 with 1 remainder
24 ÷ 2 = 12 with 0 remainder
12 ÷ 2 = 6 with 0 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 30440 octal to binary:

30440 octal = 11000100100000 binary
