What are the required steps to convert base 10 decimal system
number 1 415 926 826 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;
  • 1 415 926 826 ÷ 2 = 707 963 413 + 0;
  • 707 963 413 ÷ 2 = 353 981 706 + 1;
  • 353 981 706 ÷ 2 = 176 990 853 + 0;
  • 176 990 853 ÷ 2 = 88 495 426 + 1;
  • 88 495 426 ÷ 2 = 44 247 713 + 0;
  • 44 247 713 ÷ 2 = 22 123 856 + 1;
  • 22 123 856 ÷ 2 = 11 061 928 + 0;
  • 11 061 928 ÷ 2 = 5 530 964 + 0;
  • 5 530 964 ÷ 2 = 2 765 482 + 0;
  • 2 765 482 ÷ 2 = 1 382 741 + 0;
  • 1 382 741 ÷ 2 = 691 370 + 1;
  • 691 370 ÷ 2 = 345 685 + 0;
  • 345 685 ÷ 2 = 172 842 + 1;
  • 172 842 ÷ 2 = 86 421 + 0;
  • 86 421 ÷ 2 = 43 210 + 1;
  • 43 210 ÷ 2 = 21 605 + 0;
  • 21 605 ÷ 2 = 10 802 + 1;
  • 10 802 ÷ 2 = 5 401 + 0;
  • 5 401 ÷ 2 = 2 700 + 1;
  • 2 700 ÷ 2 = 1 350 + 0;
  • 1 350 ÷ 2 = 675 + 0;
  • 675 ÷ 2 = 337 + 1;
  • 337 ÷ 2 = 168 + 1;
  • 168 ÷ 2 = 84 + 0;
  • 84 ÷ 2 = 42 + 0;
  • 42 ÷ 2 = 21 + 0;
  • 21 ÷ 2 = 10 + 1;
  • 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.

1 415 926 826(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 415 926 826 (base 10) = 101 0100 0110 0101 0101 0100 0010 1010 (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)
