What are the required steps to convert base 10 decimal system
number 2 987 243 741 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;
  • 2 987 243 741 ÷ 2 = 1 493 621 870 + 1;
  • 1 493 621 870 ÷ 2 = 746 810 935 + 0;
  • 746 810 935 ÷ 2 = 373 405 467 + 1;
  • 373 405 467 ÷ 2 = 186 702 733 + 1;
  • 186 702 733 ÷ 2 = 93 351 366 + 1;
  • 93 351 366 ÷ 2 = 46 675 683 + 0;
  • 46 675 683 ÷ 2 = 23 337 841 + 1;
  • 23 337 841 ÷ 2 = 11 668 920 + 1;
  • 11 668 920 ÷ 2 = 5 834 460 + 0;
  • 5 834 460 ÷ 2 = 2 917 230 + 0;
  • 2 917 230 ÷ 2 = 1 458 615 + 0;
  • 1 458 615 ÷ 2 = 729 307 + 1;
  • 729 307 ÷ 2 = 364 653 + 1;
  • 364 653 ÷ 2 = 182 326 + 1;
  • 182 326 ÷ 2 = 91 163 + 0;
  • 91 163 ÷ 2 = 45 581 + 1;
  • 45 581 ÷ 2 = 22 790 + 1;
  • 22 790 ÷ 2 = 11 395 + 0;
  • 11 395 ÷ 2 = 5 697 + 1;
  • 5 697 ÷ 2 = 2 848 + 1;
  • 2 848 ÷ 2 = 1 424 + 0;
  • 1 424 ÷ 2 = 712 + 0;
  • 712 ÷ 2 = 356 + 0;
  • 356 ÷ 2 = 178 + 0;
  • 178 ÷ 2 = 89 + 0;
  • 89 ÷ 2 = 44 + 1;
  • 44 ÷ 2 = 22 + 0;
  • 22 ÷ 2 = 11 + 0;
  • 11 ÷ 2 = 5 + 1;
  • 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.

2 987 243 741(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 987 243 741 (base 10) = 1011 0010 0000 1101 1011 1000 1101 1101 (base 2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.


How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base 10 to base 2

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
  • 55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
