What are the required steps to convert base 10 decimal system
number 241 540 867 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;
- 241 540 867 ÷ 2 = 120 770 433 + 1;
- 120 770 433 ÷ 2 = 60 385 216 + 1;
- 60 385 216 ÷ 2 = 30 192 608 + 0;
- 30 192 608 ÷ 2 = 15 096 304 + 0;
- 15 096 304 ÷ 2 = 7 548 152 + 0;
- 7 548 152 ÷ 2 = 3 774 076 + 0;
- 3 774 076 ÷ 2 = 1 887 038 + 0;
- 1 887 038 ÷ 2 = 943 519 + 0;
- 943 519 ÷ 2 = 471 759 + 1;
- 471 759 ÷ 2 = 235 879 + 1;
- 235 879 ÷ 2 = 117 939 + 1;
- 117 939 ÷ 2 = 58 969 + 1;
- 58 969 ÷ 2 = 29 484 + 1;
- 29 484 ÷ 2 = 14 742 + 0;
- 14 742 ÷ 2 = 7 371 + 0;
- 7 371 ÷ 2 = 3 685 + 1;
- 3 685 ÷ 2 = 1 842 + 1;
- 1 842 ÷ 2 = 921 + 0;
- 921 ÷ 2 = 460 + 1;
- 460 ÷ 2 = 230 + 0;
- 230 ÷ 2 = 115 + 0;
- 115 ÷ 2 = 57 + 1;
- 57 ÷ 2 = 28 + 1;
- 28 ÷ 2 = 14 + 0;
- 14 ÷ 2 = 7 + 0;
- 7 ÷ 2 = 3 + 1;
- 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.
241 540 867(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
241 540 867 (base 10) = 1110 0110 0101 1001 1111 0000 0011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
