What are the required steps to convert base 10 decimal system
number 1 804 289 173 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;
  • 1 804 289 173 ÷ 2 = 902 144 586 + 1;
  • 902 144 586 ÷ 2 = 451 072 293 + 0;
  • 451 072 293 ÷ 2 = 225 536 146 + 1;
  • 225 536 146 ÷ 2 = 112 768 073 + 0;
  • 112 768 073 ÷ 2 = 56 384 036 + 1;
  • 56 384 036 ÷ 2 = 28 192 018 + 0;
  • 28 192 018 ÷ 2 = 14 096 009 + 0;
  • 14 096 009 ÷ 2 = 7 048 004 + 1;
  • 7 048 004 ÷ 2 = 3 524 002 + 0;
  • 3 524 002 ÷ 2 = 1 762 001 + 0;
  • 1 762 001 ÷ 2 = 881 000 + 1;
  • 881 000 ÷ 2 = 440 500 + 0;
  • 440 500 ÷ 2 = 220 250 + 0;
  • 220 250 ÷ 2 = 110 125 + 0;
  • 110 125 ÷ 2 = 55 062 + 1;
  • 55 062 ÷ 2 = 27 531 + 0;
  • 27 531 ÷ 2 = 13 765 + 1;
  • 13 765 ÷ 2 = 6 882 + 1;
  • 6 882 ÷ 2 = 3 441 + 0;
  • 3 441 ÷ 2 = 1 720 + 1;
  • 1 720 ÷ 2 = 860 + 0;
  • 860 ÷ 2 = 430 + 0;
  • 430 ÷ 2 = 215 + 0;
  • 215 ÷ 2 = 107 + 1;
  • 107 ÷ 2 = 53 + 1;
  • 53 ÷ 2 = 26 + 1;
  • 26 ÷ 2 = 13 + 0;
  • 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 number:

Take all the remainders starting from the bottom of the list constructed above.

1 804 289 173(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 804 289 173 (base 10) = 110 1011 1000 1011 0100 0100 1001 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)
