What are the required steps to convert base 10 decimal system
number 1 101 109 836 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;
  • 1 101 109 836 ÷ 2 = 550 554 918 + 0;
  • 550 554 918 ÷ 2 = 275 277 459 + 0;
  • 275 277 459 ÷ 2 = 137 638 729 + 1;
  • 137 638 729 ÷ 2 = 68 819 364 + 1;
  • 68 819 364 ÷ 2 = 34 409 682 + 0;
  • 34 409 682 ÷ 2 = 17 204 841 + 0;
  • 17 204 841 ÷ 2 = 8 602 420 + 1;
  • 8 602 420 ÷ 2 = 4 301 210 + 0;
  • 4 301 210 ÷ 2 = 2 150 605 + 0;
  • 2 150 605 ÷ 2 = 1 075 302 + 1;
  • 1 075 302 ÷ 2 = 537 651 + 0;
  • 537 651 ÷ 2 = 268 825 + 1;
  • 268 825 ÷ 2 = 134 412 + 1;
  • 134 412 ÷ 2 = 67 206 + 0;
  • 67 206 ÷ 2 = 33 603 + 0;
  • 33 603 ÷ 2 = 16 801 + 1;
  • 16 801 ÷ 2 = 8 400 + 1;
  • 8 400 ÷ 2 = 4 200 + 0;
  • 4 200 ÷ 2 = 2 100 + 0;
  • 2 100 ÷ 2 = 1 050 + 0;
  • 1 050 ÷ 2 = 525 + 0;
  • 525 ÷ 2 = 262 + 1;
  • 262 ÷ 2 = 131 + 0;
  • 131 ÷ 2 = 65 + 1;
  • 65 ÷ 2 = 32 + 1;
  • 32 ÷ 2 = 16 + 0;
  • 16 ÷ 2 = 8 + 0;
  • 8 ÷ 2 = 4 + 0;
  • 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.

1 101 109 836(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 101 109 836 (base 10) = 100 0001 1010 0001 1001 1010 0100 1100 (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)
