Here we will show you how to convert the octal number 20010 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 20010 from octal to binary are explained below.
Step 1)
Multiply the last digit in 20010 by 8⁰, multiply the second to last digit in 20010 by 8¹, multiply the third to last digit in 20010 by 8², multiply the fourth to last digit in 20010 by 8³, and so on, until all the digits are used:
0 × 8⁰ = 0
1 × 8¹ = 8
0 × 8² = 0
0 × 8³ = 0
2 × 8⁴ = 8192
Step 2)
Next, we add up all the products we got from Step 1, like this:
0 + 8 + 0 + 0 + 8192 = 8200
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.
8200 ÷ 2 = 4100 with 0 remainder
4100 ÷ 2 = 2050 with 0 remainder
2050 ÷ 2 = 1025 with 0 remainder
1025 ÷ 2 = 512 with 1 remainder
512 ÷ 2 = 256 with 0 remainder
256 ÷ 2 = 128 with 0 remainder
128 ÷ 2 = 64 with 0 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 20010 octal to binary:
20010 octal = 10000000001000 binary
