5311 octal to binary

Here we will show you how to convert the octal number 5311 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 5311 from octal to binary are explained below.

Step 1)
Multiply the last digit in 5311 by 8⁰, multiply the second to last digit in 5311 by 8¹, multiply the third to last digit in 5311 by 8², multiply the fourth to last digit in 5311 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
1 × 8¹ = 8
3 × 8² = 192
5 × 8³ = 2560

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

1 + 8 + 192 + 2560 = 2761

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.

2761 ÷ 2 = 1380 with 1 remainder
1380 ÷ 2 = 690 with 0 remainder
690 ÷ 2 = 345 with 0 remainder
345 ÷ 2 = 172 with 1 remainder
172 ÷ 2 = 86 with 0 remainder
86 ÷ 2 = 43 with 0 remainder
43 ÷ 2 = 21 with 1 remainder
21 ÷ 2 = 10 with 1 remainder
10 ÷ 2 = 5 with 0 remainder
5 ÷ 2 = 2 with 1 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 5311 octal to binary:

5311 octal = 101011001001 binary
