What are the required steps to convert base 10 decimal system
number 17 777 990 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;
- 17 777 990 ÷ 2 = 8 888 995 + 0;
- 8 888 995 ÷ 2 = 4 444 497 + 1;
- 4 444 497 ÷ 2 = 2 222 248 + 1;
- 2 222 248 ÷ 2 = 1 111 124 + 0;
- 1 111 124 ÷ 2 = 555 562 + 0;
- 555 562 ÷ 2 = 277 781 + 0;
- 277 781 ÷ 2 = 138 890 + 1;
- 138 890 ÷ 2 = 69 445 + 0;
- 69 445 ÷ 2 = 34 722 + 1;
- 34 722 ÷ 2 = 17 361 + 0;
- 17 361 ÷ 2 = 8 680 + 1;
- 8 680 ÷ 2 = 4 340 + 0;
- 4 340 ÷ 2 = 2 170 + 0;
- 2 170 ÷ 2 = 1 085 + 0;
- 1 085 ÷ 2 = 542 + 1;
- 542 ÷ 2 = 271 + 0;
- 271 ÷ 2 = 135 + 1;
- 135 ÷ 2 = 67 + 1;
- 67 ÷ 2 = 33 + 1;
- 33 ÷ 2 = 16 + 1;
- 16 ÷ 2 = 8 + 0;
- 8 ÷ 2 = 4 + 0;
- 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.
17 777 990(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
17 777 990 (base 10) = 1 0000 1111 0100 0101 0100 0110 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
