What are the required steps to convert base 10 decimal system
number 3 532 609 361 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;
  • 3 532 609 361 ÷ 2 = 1 766 304 680 + 1;
  • 1 766 304 680 ÷ 2 = 883 152 340 + 0;
  • 883 152 340 ÷ 2 = 441 576 170 + 0;
  • 441 576 170 ÷ 2 = 220 788 085 + 0;
  • 220 788 085 ÷ 2 = 110 394 042 + 1;
  • 110 394 042 ÷ 2 = 55 197 021 + 0;
  • 55 197 021 ÷ 2 = 27 598 510 + 1;
  • 27 598 510 ÷ 2 = 13 799 255 + 0;
  • 13 799 255 ÷ 2 = 6 899 627 + 1;
  • 6 899 627 ÷ 2 = 3 449 813 + 1;
  • 3 449 813 ÷ 2 = 1 724 906 + 1;
  • 1 724 906 ÷ 2 = 862 453 + 0;
  • 862 453 ÷ 2 = 431 226 + 1;
  • 431 226 ÷ 2 = 215 613 + 0;
  • 215 613 ÷ 2 = 107 806 + 1;
  • 107 806 ÷ 2 = 53 903 + 0;
  • 53 903 ÷ 2 = 26 951 + 1;
  • 26 951 ÷ 2 = 13 475 + 1;
  • 13 475 ÷ 2 = 6 737 + 1;
  • 6 737 ÷ 2 = 3 368 + 1;
  • 3 368 ÷ 2 = 1 684 + 0;
  • 1 684 ÷ 2 = 842 + 0;
  • 842 ÷ 2 = 421 + 0;
  • 421 ÷ 2 = 210 + 1;
  • 210 ÷ 2 = 105 + 0;
  • 105 ÷ 2 = 52 + 1;
  • 52 ÷ 2 = 26 + 0;
  • 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.

3 532 609 361(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 532 609 361 (base 10) = 1101 0010 1000 1111 0101 0111 0101 0001 (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)
