What are the required steps to convert base 10 decimal system
number 3 381 621 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;
- 3 381 621 ÷ 2 = 1 690 810 + 1;
- 1 690 810 ÷ 2 = 845 405 + 0;
- 845 405 ÷ 2 = 422 702 + 1;
- 422 702 ÷ 2 = 211 351 + 0;
- 211 351 ÷ 2 = 105 675 + 1;
- 105 675 ÷ 2 = 52 837 + 1;
- 52 837 ÷ 2 = 26 418 + 1;
- 26 418 ÷ 2 = 13 209 + 0;
- 13 209 ÷ 2 = 6 604 + 1;
- 6 604 ÷ 2 = 3 302 + 0;
- 3 302 ÷ 2 = 1 651 + 0;
- 1 651 ÷ 2 = 825 + 1;
- 825 ÷ 2 = 412 + 1;
- 412 ÷ 2 = 206 + 0;
- 206 ÷ 2 = 103 + 0;
- 103 ÷ 2 = 51 + 1;
- 51 ÷ 2 = 25 + 1;
- 25 ÷ 2 = 12 + 1;
- 12 ÷ 2 = 6 + 0;
- 6 ÷ 2 = 3 + 0;
- 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.
3 381 621(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
3 381 621 (base 10) = 11 0011 1001 1001 0111 0101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
