What are the required steps to convert base 10 decimal system
number 1 424 921 909 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;
- 1 424 921 909 ÷ 2 = 712 460 954 + 1;
- 712 460 954 ÷ 2 = 356 230 477 + 0;
- 356 230 477 ÷ 2 = 178 115 238 + 1;
- 178 115 238 ÷ 2 = 89 057 619 + 0;
- 89 057 619 ÷ 2 = 44 528 809 + 1;
- 44 528 809 ÷ 2 = 22 264 404 + 1;
- 22 264 404 ÷ 2 = 11 132 202 + 0;
- 11 132 202 ÷ 2 = 5 566 101 + 0;
- 5 566 101 ÷ 2 = 2 783 050 + 1;
- 2 783 050 ÷ 2 = 1 391 525 + 0;
- 1 391 525 ÷ 2 = 695 762 + 1;
- 695 762 ÷ 2 = 347 881 + 0;
- 347 881 ÷ 2 = 173 940 + 1;
- 173 940 ÷ 2 = 86 970 + 0;
- 86 970 ÷ 2 = 43 485 + 0;
- 43 485 ÷ 2 = 21 742 + 1;
- 21 742 ÷ 2 = 10 871 + 0;
- 10 871 ÷ 2 = 5 435 + 1;
- 5 435 ÷ 2 = 2 717 + 1;
- 2 717 ÷ 2 = 1 358 + 1;
- 1 358 ÷ 2 = 679 + 0;
- 679 ÷ 2 = 339 + 1;
- 339 ÷ 2 = 169 + 1;
- 169 ÷ 2 = 84 + 1;
- 84 ÷ 2 = 42 + 0;
- 42 ÷ 2 = 21 + 0;
- 21 ÷ 2 = 10 + 1;
- 10 ÷ 2 = 5 + 0;
- 5 ÷ 2 = 2 + 1;
- 2 ÷ 2 = 1 + 0;
- 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.
1 424 921 909(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
1 424 921 909 (base 10) = 101 0100 1110 1110 1001 0101 0011 0101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
