What are the required steps to convert base 10 decimal system
number 2 987 243 216 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;
  • 2 987 243 216 ÷ 2 = 1 493 621 608 + 0;
  • 1 493 621 608 ÷ 2 = 746 810 804 + 0;
  • 746 810 804 ÷ 2 = 373 405 402 + 0;
  • 373 405 402 ÷ 2 = 186 702 701 + 0;
  • 186 702 701 ÷ 2 = 93 351 350 + 1;
  • 93 351 350 ÷ 2 = 46 675 675 + 0;
  • 46 675 675 ÷ 2 = 23 337 837 + 1;
  • 23 337 837 ÷ 2 = 11 668 918 + 1;
  • 11 668 918 ÷ 2 = 5 834 459 + 0;
  • 5 834 459 ÷ 2 = 2 917 229 + 1;
  • 2 917 229 ÷ 2 = 1 458 614 + 1;
  • 1 458 614 ÷ 2 = 729 307 + 0;
  • 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.

2 987 243 216(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 987 243 216 (base 10) = 1011 0010 0000 1101 1011 0110 1101 0000 (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)
