What are the required steps to convert base 10 decimal system
number 2 471 321 400 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;
  • 2 471 321 400 ÷ 2 = 1 235 660 700 + 0;
  • 1 235 660 700 ÷ 2 = 617 830 350 + 0;
  • 617 830 350 ÷ 2 = 308 915 175 + 0;
  • 308 915 175 ÷ 2 = 154 457 587 + 1;
  • 154 457 587 ÷ 2 = 77 228 793 + 1;
  • 77 228 793 ÷ 2 = 38 614 396 + 1;
  • 38 614 396 ÷ 2 = 19 307 198 + 0;
  • 19 307 198 ÷ 2 = 9 653 599 + 0;
  • 9 653 599 ÷ 2 = 4 826 799 + 1;
  • 4 826 799 ÷ 2 = 2 413 399 + 1;
  • 2 413 399 ÷ 2 = 1 206 699 + 1;
  • 1 206 699 ÷ 2 = 603 349 + 1;
  • 603 349 ÷ 2 = 301 674 + 1;
  • 301 674 ÷ 2 = 150 837 + 0;
  • 150 837 ÷ 2 = 75 418 + 1;
  • 75 418 ÷ 2 = 37 709 + 0;
  • 37 709 ÷ 2 = 18 854 + 1;
  • 18 854 ÷ 2 = 9 427 + 0;
  • 9 427 ÷ 2 = 4 713 + 1;
  • 4 713 ÷ 2 = 2 356 + 1;
  • 2 356 ÷ 2 = 1 178 + 0;
  • 1 178 ÷ 2 = 589 + 0;
  • 589 ÷ 2 = 294 + 1;
  • 294 ÷ 2 = 147 + 0;
  • 147 ÷ 2 = 73 + 1;
  • 73 ÷ 2 = 36 + 1;
  • 36 ÷ 2 = 18 + 0;
  • 18 ÷ 2 = 9 + 0;
  • 9 ÷ 2 = 4 + 1;
  • 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.

2 471 321 400(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 471 321 400 (base 10) = 1001 0011 0100 1101 0101 1111 0011 1000 (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)
