40240 octal to binary

Here we will show you how to convert the octal number 40240 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 40240 from octal to binary are explained below.

Step 1)
Multiply the last digit in 40240 by 8⁰, multiply the second to last digit in 40240 by 8¹, multiply the third to last digit in 40240 by 8², multiply the fourth to last digit in 40240 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
4 × 8¹ = 32
2 × 8² = 128
0 × 8³ = 0
4 × 8⁴ = 16384

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

0 + 32 + 128 + 0 + 16384 = 16544

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.

16544 ÷ 2 = 8272 with 0 remainder
8272 ÷ 2 = 4136 with 0 remainder
4136 ÷ 2 = 2068 with 0 remainder
2068 ÷ 2 = 1034 with 0 remainder
1034 ÷ 2 = 517 with 0 remainder
517 ÷ 2 = 258 with 1 remainder
258 ÷ 2 = 129 with 0 remainder
129 ÷ 2 = 64 with 1 remainder
64 ÷ 2 = 32 with 0 remainder
32 ÷ 2 = 16 with 0 remainder
16 ÷ 2 = 8 with 0 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 40240 octal to binary:

40240 octal = 100000010100000 binary
