What are the required steps to convert base 10 decimal system
number 327 687 867 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;
- 327 687 867 ÷ 2 = 163 843 933 + 1;
- 163 843 933 ÷ 2 = 81 921 966 + 1;
- 81 921 966 ÷ 2 = 40 960 983 + 0;
- 40 960 983 ÷ 2 = 20 480 491 + 1;
- 20 480 491 ÷ 2 = 10 240 245 + 1;
- 10 240 245 ÷ 2 = 5 120 122 + 1;
- 5 120 122 ÷ 2 = 2 560 061 + 0;
- 2 560 061 ÷ 2 = 1 280 030 + 1;
- 1 280 030 ÷ 2 = 640 015 + 0;
- 640 015 ÷ 2 = 320 007 + 1;
- 320 007 ÷ 2 = 160 003 + 1;
- 160 003 ÷ 2 = 80 001 + 1;
- 80 001 ÷ 2 = 40 000 + 1;
- 40 000 ÷ 2 = 20 000 + 0;
- 20 000 ÷ 2 = 10 000 + 0;
- 10 000 ÷ 2 = 5 000 + 0;
- 5 000 ÷ 2 = 2 500 + 0;
- 2 500 ÷ 2 = 1 250 + 0;
- 1 250 ÷ 2 = 625 + 0;
- 625 ÷ 2 = 312 + 1;
- 312 ÷ 2 = 156 + 0;
- 156 ÷ 2 = 78 + 0;
- 78 ÷ 2 = 39 + 0;
- 39 ÷ 2 = 19 + 1;
- 19 ÷ 2 = 9 + 1;
- 9 ÷ 2 = 4 + 1;
- 4 ÷ 2 = 2 + 0;
- 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.
327 687 867(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
327 687 867 (base 10) = 1 0011 1000 1000 0001 1110 1011 1011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
