40505 octal to binary

Here we will show you how to convert the octal number 40505 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 40505 from octal to binary are explained below.

Step 1)
Multiply the last digit in 40505 by 8⁰, multiply the second to last digit in 40505 by 8¹, multiply the third to last digit in 40505 by 8², multiply the fourth to last digit in 40505 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
0 × 8¹ = 0
5 × 8² = 320
0 × 8³ = 0
4 × 8⁴ = 16384

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

5 + 0 + 320 + 0 + 16384 = 16709

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.

16709 ÷ 2 = 8354 with 1 remainder
8354 ÷ 2 = 4177 with 0 remainder
4177 ÷ 2 = 2088 with 1 remainder
2088 ÷ 2 = 1044 with 0 remainder
1044 ÷ 2 = 522 with 0 remainder
522 ÷ 2 = 261 with 0 remainder
261 ÷ 2 = 130 with 1 remainder
130 ÷ 2 = 65 with 0 remainder
65 ÷ 2 = 32 with 1 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 40505 octal to binary:

40505 octal = 100000101000101 binary
