What are the required steps to convert base 10 decimal system
number 7 357 240 to base 2 unsigned binary equivalent?
- A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.
1. Divide the number repeatedly by 2:
Keep track of each remainder.
Stop when you get a quotient that is equal to zero.
- division = quotient + remainder;
- 7 357 240 ÷ 2 = 3 678 620 + 0;
- 3 678 620 ÷ 2 = 1 839 310 + 0;
- 1 839 310 ÷ 2 = 919 655 + 0;
- 919 655 ÷ 2 = 459 827 + 1;
- 459 827 ÷ 2 = 229 913 + 1;
- 229 913 ÷ 2 = 114 956 + 1;
- 114 956 ÷ 2 = 57 478 + 0;
- 57 478 ÷ 2 = 28 739 + 0;
- 28 739 ÷ 2 = 14 369 + 1;
- 14 369 ÷ 2 = 7 184 + 1;
- 7 184 ÷ 2 = 3 592 + 0;
- 3 592 ÷ 2 = 1 796 + 0;
- 1 796 ÷ 2 = 898 + 0;
- 898 ÷ 2 = 449 + 0;
- 449 ÷ 2 = 224 + 1;
- 224 ÷ 2 = 112 + 0;
- 112 ÷ 2 = 56 + 0;
- 56 ÷ 2 = 28 + 0;
- 28 ÷ 2 = 14 + 0;
- 14 ÷ 2 = 7 + 0;
- 7 ÷ 2 = 3 + 1;
- 3 ÷ 2 = 1 + 1;
- 1 ÷ 2 = 0 + 1;
2. Construct the base 2 representation of the positive number:
Take all the remainders starting from the bottom of the list constructed above.
7 357 240(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
7 357 240 (base 10) = 111 0000 0100 0011 0011 1000 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
