What are the required steps to convert base 10 decimal system
number 1 423 235 554 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;
  • 1 423 235 554 ÷ 2 = 711 617 777 + 0;
  • 711 617 777 ÷ 2 = 355 808 888 + 1;
  • 355 808 888 ÷ 2 = 177 904 444 + 0;
  • 177 904 444 ÷ 2 = 88 952 222 + 0;
  • 88 952 222 ÷ 2 = 44 476 111 + 0;
  • 44 476 111 ÷ 2 = 22 238 055 + 1;
  • 22 238 055 ÷ 2 = 11 119 027 + 1;
  • 11 119 027 ÷ 2 = 5 559 513 + 1;
  • 5 559 513 ÷ 2 = 2 779 756 + 1;
  • 2 779 756 ÷ 2 = 1 389 878 + 0;
  • 1 389 878 ÷ 2 = 694 939 + 0;
  • 694 939 ÷ 2 = 347 469 + 1;
  • 347 469 ÷ 2 = 173 734 + 1;
  • 173 734 ÷ 2 = 86 867 + 0;
  • 86 867 ÷ 2 = 43 433 + 1;
  • 43 433 ÷ 2 = 21 716 + 1;
  • 21 716 ÷ 2 = 10 858 + 0;
  • 10 858 ÷ 2 = 5 429 + 0;
  • 5 429 ÷ 2 = 2 714 + 1;
  • 2 714 ÷ 2 = 1 357 + 0;
  • 1 357 ÷ 2 = 678 + 1;
  • 678 ÷ 2 = 339 + 0;
  • 339 ÷ 2 = 169 + 1;
  • 169 ÷ 2 = 84 + 1;
  • 84 ÷ 2 = 42 + 0;
  • 42 ÷ 2 = 21 + 0;
  • 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.

1 423 235 554(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 423 235 554 (base 10) = 101 0100 1101 0100 1101 1001 1110 0010 (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)
