What are the required steps to convert base 10 decimal system
number 5 432 543 215 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;
  • 5 432 543 215 ÷ 2 = 2 716 271 607 + 1;
  • 2 716 271 607 ÷ 2 = 1 358 135 803 + 1;
  • 1 358 135 803 ÷ 2 = 679 067 901 + 1;
  • 679 067 901 ÷ 2 = 339 533 950 + 1;
  • 339 533 950 ÷ 2 = 169 766 975 + 0;
  • 169 766 975 ÷ 2 = 84 883 487 + 1;
  • 84 883 487 ÷ 2 = 42 441 743 + 1;
  • 42 441 743 ÷ 2 = 21 220 871 + 1;
  • 21 220 871 ÷ 2 = 10 610 435 + 1;
  • 10 610 435 ÷ 2 = 5 305 217 + 1;
  • 5 305 217 ÷ 2 = 2 652 608 + 1;
  • 2 652 608 ÷ 2 = 1 326 304 + 0;
  • 1 326 304 ÷ 2 = 663 152 + 0;
  • 663 152 ÷ 2 = 331 576 + 0;
  • 331 576 ÷ 2 = 165 788 + 0;
  • 165 788 ÷ 2 = 82 894 + 0;
  • 82 894 ÷ 2 = 41 447 + 0;
  • 41 447 ÷ 2 = 20 723 + 1;
  • 20 723 ÷ 2 = 10 361 + 1;
  • 10 361 ÷ 2 = 5 180 + 1;
  • 5 180 ÷ 2 = 2 590 + 0;
  • 2 590 ÷ 2 = 1 295 + 0;
  • 1 295 ÷ 2 = 647 + 1;
  • 647 ÷ 2 = 323 + 1;
  • 323 ÷ 2 = 161 + 1;
  • 161 ÷ 2 = 80 + 1;
  • 80 ÷ 2 = 40 + 0;
  • 40 ÷ 2 = 20 + 0;
  • 20 ÷ 2 = 10 + 0;
  • 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.

5 432 543 215(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

5 432 543 215 (base 10) = 1 0100 0011 1100 1110 0000 0111 1110 1111 (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)
