40212 octal to binary

Here we will show you how to convert the octal number 40212 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 40212 from octal to binary are explained below.

Step 1)
Multiply the last digit in 40212 by 8⁰, multiply the second to last digit in 40212 by 8¹, multiply the third to last digit in 40212 by 8², multiply the fourth to last digit in 40212 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
1 × 8¹ = 8
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:

2 + 8 + 128 + 0 + 16384 = 16522

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.

16522 ÷ 2 = 8261 with 0 remainder
8261 ÷ 2 = 4130 with 1 remainder
4130 ÷ 2 = 2065 with 0 remainder
2065 ÷ 2 = 1032 with 1 remainder
1032 ÷ 2 = 516 with 0 remainder
516 ÷ 2 = 258 with 0 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 40212 octal to binary:

40212 octal = 100000010001010 binary
