What are the required steps to convert base 10 decimal system
number 3 221 225 500 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;
  • 3 221 225 500 ÷ 2 = 1 610 612 750 + 0;
  • 1 610 612 750 ÷ 2 = 805 306 375 + 0;
  • 805 306 375 ÷ 2 = 402 653 187 + 1;
  • 402 653 187 ÷ 2 = 201 326 593 + 1;
  • 201 326 593 ÷ 2 = 100 663 296 + 1;
  • 100 663 296 ÷ 2 = 50 331 648 + 0;
  • 50 331 648 ÷ 2 = 25 165 824 + 0;
  • 25 165 824 ÷ 2 = 12 582 912 + 0;
  • 12 582 912 ÷ 2 = 6 291 456 + 0;
  • 6 291 456 ÷ 2 = 3 145 728 + 0;
  • 3 145 728 ÷ 2 = 1 572 864 + 0;
  • 1 572 864 ÷ 2 = 786 432 + 0;
  • 786 432 ÷ 2 = 393 216 + 0;
  • 393 216 ÷ 2 = 196 608 + 0;
  • 196 608 ÷ 2 = 98 304 + 0;
  • 98 304 ÷ 2 = 49 152 + 0;
  • 49 152 ÷ 2 = 24 576 + 0;
  • 24 576 ÷ 2 = 12 288 + 0;
  • 12 288 ÷ 2 = 6 144 + 0;
  • 6 144 ÷ 2 = 3 072 + 0;
  • 3 072 ÷ 2 = 1 536 + 0;
  • 1 536 ÷ 2 = 768 + 0;
  • 768 ÷ 2 = 384 + 0;
  • 384 ÷ 2 = 192 + 0;
  • 192 ÷ 2 = 96 + 0;
  • 96 ÷ 2 = 48 + 0;
  • 48 ÷ 2 = 24 + 0;
  • 24 ÷ 2 = 12 + 0;
  • 12 ÷ 2 = 6 + 0;
  • 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.

3 221 225 500(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 221 225 500 (base 10) = 1100 0000 0000 0000 0000 0000 0001 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)
