What are the required steps to convert base 10 decimal system
number 2 903 507 509 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;
  • 2 903 507 509 ÷ 2 = 1 451 753 754 + 1;
  • 1 451 753 754 ÷ 2 = 725 876 877 + 0;
  • 725 876 877 ÷ 2 = 362 938 438 + 1;
  • 362 938 438 ÷ 2 = 181 469 219 + 0;
  • 181 469 219 ÷ 2 = 90 734 609 + 1;
  • 90 734 609 ÷ 2 = 45 367 304 + 1;
  • 45 367 304 ÷ 2 = 22 683 652 + 0;
  • 22 683 652 ÷ 2 = 11 341 826 + 0;
  • 11 341 826 ÷ 2 = 5 670 913 + 0;
  • 5 670 913 ÷ 2 = 2 835 456 + 1;
  • 2 835 456 ÷ 2 = 1 417 728 + 0;
  • 1 417 728 ÷ 2 = 708 864 + 0;
  • 708 864 ÷ 2 = 354 432 + 0;
  • 354 432 ÷ 2 = 177 216 + 0;
  • 177 216 ÷ 2 = 88 608 + 0;
  • 88 608 ÷ 2 = 44 304 + 0;
  • 44 304 ÷ 2 = 22 152 + 0;
  • 22 152 ÷ 2 = 11 076 + 0;
  • 11 076 ÷ 2 = 5 538 + 0;
  • 5 538 ÷ 2 = 2 769 + 0;
  • 2 769 ÷ 2 = 1 384 + 1;
  • 1 384 ÷ 2 = 692 + 0;
  • 692 ÷ 2 = 346 + 0;
  • 346 ÷ 2 = 173 + 0;
  • 173 ÷ 2 = 86 + 1;
  • 86 ÷ 2 = 43 + 0;
  • 43 ÷ 2 = 21 + 1;
  • 21 ÷ 2 = 10 + 1;
  • 10 ÷ 2 = 5 + 0;
  • 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.

2 903 507 509(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 903 507 509 (base 10) = 1010 1101 0001 0000 0000 0010 0011 0101 (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)
