What are the required steps to convert base 10 decimal system
number 648 170 072 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;
- 648 170 072 ÷ 2 = 324 085 036 + 0;
- 324 085 036 ÷ 2 = 162 042 518 + 0;
- 162 042 518 ÷ 2 = 81 021 259 + 0;
- 81 021 259 ÷ 2 = 40 510 629 + 1;
- 40 510 629 ÷ 2 = 20 255 314 + 1;
- 20 255 314 ÷ 2 = 10 127 657 + 0;
- 10 127 657 ÷ 2 = 5 063 828 + 1;
- 5 063 828 ÷ 2 = 2 531 914 + 0;
- 2 531 914 ÷ 2 = 1 265 957 + 0;
- 1 265 957 ÷ 2 = 632 978 + 1;
- 632 978 ÷ 2 = 316 489 + 0;
- 316 489 ÷ 2 = 158 244 + 1;
- 158 244 ÷ 2 = 79 122 + 0;
- 79 122 ÷ 2 = 39 561 + 0;
- 39 561 ÷ 2 = 19 780 + 1;
- 19 780 ÷ 2 = 9 890 + 0;
- 9 890 ÷ 2 = 4 945 + 0;
- 4 945 ÷ 2 = 2 472 + 1;
- 2 472 ÷ 2 = 1 236 + 0;
- 1 236 ÷ 2 = 618 + 0;
- 618 ÷ 2 = 309 + 0;
- 309 ÷ 2 = 154 + 1;
- 154 ÷ 2 = 77 + 0;
- 77 ÷ 2 = 38 + 1;
- 38 ÷ 2 = 19 + 0;
- 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.
