77212 octal to binary

Here we will show you how to convert the octal number 77212 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 77212 from octal to binary are explained below.

Step 1)
Multiply the last digit in 77212 by 8⁰, multiply the second to last digit in 77212 by 8¹, multiply the third to last digit in 77212 by 8², multiply the fourth to last digit in 77212 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
1 × 8¹ = 8
2 × 8² = 128
7 × 8³ = 3584
7 × 8⁴ = 28672

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

2 + 8 + 128 + 3584 + 28672 = 32394

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.

32394 ÷ 2 = 16197 with 0 remainder
16197 ÷ 2 = 8098 with 1 remainder
8098 ÷ 2 = 4049 with 0 remainder
4049 ÷ 2 = 2024 with 1 remainder
2024 ÷ 2 = 1012 with 0 remainder
1012 ÷ 2 = 506 with 0 remainder
506 ÷ 2 = 253 with 0 remainder
253 ÷ 2 = 126 with 1 remainder
126 ÷ 2 = 63 with 0 remainder
63 ÷ 2 = 31 with 1 remainder
31 ÷ 2 = 15 with 1 remainder
15 ÷ 2 = 7 with 1 remainder
7 ÷ 2 = 3 with 1 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 77212 octal to binary:

77212 octal = 111111010001010 binary
