40342 octal to binary

Here we will show you how to convert the octal number 40342 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 40342 from octal to binary are explained below.

Step 1)
Multiply the last digit in 40342 by 8⁰, multiply the second to last digit in 40342 by 8¹, multiply the third to last digit in 40342 by 8², multiply the fourth to last digit in 40342 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
4 × 8¹ = 32
3 × 8² = 192
0 × 8³ = 0
4 × 8⁴ = 16384

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

2 + 32 + 192 + 0 + 16384 = 16610

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.

16610 ÷ 2 = 8305 with 0 remainder
8305 ÷ 2 = 4152 with 1 remainder
4152 ÷ 2 = 2076 with 0 remainder
2076 ÷ 2 = 1038 with 0 remainder
1038 ÷ 2 = 519 with 0 remainder
519 ÷ 2 = 259 with 1 remainder
259 ÷ 2 = 129 with 1 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 40342 octal to binary:

40342 octal = 100000011100010 binary
