Here we will show you how to convert the octal number 51265 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 51265 from octal to binary are explained below.
Step 1)
Multiply the last digit in 51265 by 8⁰, multiply the second to last digit in 51265 by 8¹, multiply the third to last digit in 51265 by 8², multiply the fourth to last digit in 51265 by 8³, and so on, until all the digits are used:
5 × 8⁰ = 5
6 × 8¹ = 48
2 × 8² = 128
1 × 8³ = 512
5 × 8⁴ = 20480
Step 2)
Next, we add up all the products we got from Step 1, like this:
5 + 48 + 128 + 512 + 20480 = 21173
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.
21173 ÷ 2 = 10586 with 1 remainder
10586 ÷ 2 = 5293 with 0 remainder
5293 ÷ 2 = 2646 with 1 remainder
2646 ÷ 2 = 1323 with 0 remainder
1323 ÷ 2 = 661 with 1 remainder
661 ÷ 2 = 330 with 1 remainder
330 ÷ 2 = 165 with 0 remainder
165 ÷ 2 = 82 with 1 remainder
82 ÷ 2 = 41 with 0 remainder
41 ÷ 2 = 20 with 1 remainder
20 ÷ 2 = 10 with 0 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 51265 octal to binary:
51265 octal = 101001010110101 binary
