47240 octal to binary

Here we will show you how to convert the octal number 47240 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 47240 from octal to binary are explained below.

Step 1)
Multiply the last digit in 47240 by 8⁰, multiply the second to last digit in 47240 by 8¹, multiply the third to last digit in 47240 by 8², multiply the fourth to last digit in 47240 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
4 × 8¹ = 32
2 × 8² = 128
7 × 8³ = 3584
4 × 8⁴ = 16384

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

0 + 32 + 128 + 3584 + 16384 = 20128

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.

20128 ÷ 2 = 10064 with 0 remainder
10064 ÷ 2 = 5032 with 0 remainder
5032 ÷ 2 = 2516 with 0 remainder
2516 ÷ 2 = 1258 with 0 remainder
1258 ÷ 2 = 629 with 0 remainder
629 ÷ 2 = 314 with 1 remainder
314 ÷ 2 = 157 with 0 remainder
157 ÷ 2 = 78 with 1 remainder
78 ÷ 2 = 39 with 0 remainder
39 ÷ 2 = 19 with 1 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 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 47240 octal to binary:

47240 octal = 100111010100000 binary
