What are the required steps to convert base 10 decimal system
number 2 149 582 955 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;
  • 2 149 582 955 ÷ 2 = 1 074 791 477 + 1;
  • 1 074 791 477 ÷ 2 = 537 395 738 + 1;
  • 537 395 738 ÷ 2 = 268 697 869 + 0;
  • 268 697 869 ÷ 2 = 134 348 934 + 1;
  • 134 348 934 ÷ 2 = 67 174 467 + 0;
  • 67 174 467 ÷ 2 = 33 587 233 + 1;
  • 33 587 233 ÷ 2 = 16 793 616 + 1;
  • 16 793 616 ÷ 2 = 8 396 808 + 0;
  • 8 396 808 ÷ 2 = 4 198 404 + 0;
  • 4 198 404 ÷ 2 = 2 099 202 + 0;
  • 2 099 202 ÷ 2 = 1 049 601 + 0;
  • 1 049 601 ÷ 2 = 524 800 + 1;
  • 524 800 ÷ 2 = 262 400 + 0;
  • 262 400 ÷ 2 = 131 200 + 0;
  • 131 200 ÷ 2 = 65 600 + 0;
  • 65 600 ÷ 2 = 32 800 + 0;
  • 32 800 ÷ 2 = 16 400 + 0;
  • 16 400 ÷ 2 = 8 200 + 0;
  • 8 200 ÷ 2 = 4 100 + 0;
  • 4 100 ÷ 2 = 2 050 + 0;
  • 2 050 ÷ 2 = 1 025 + 0;
  • 1 025 ÷ 2 = 512 + 1;
  • 512 ÷ 2 = 256 + 0;
  • 256 ÷ 2 = 128 + 0;
  • 128 ÷ 2 = 64 + 0;
  • 64 ÷ 2 = 32 + 0;
  • 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.

2 149 582 955(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 149 582 955 (base 10) = 1000 0000 0010 0000 0000 1000 0110 1011 (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)
