What are the required steps to convert base 10 decimal system
number 12 345 679 207 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;

  • 1 543 209 900 ÷ 2 = 771 604 950 + 0;
  • 771 604 950 ÷ 2 = 385 802 475 + 0;
  • 385 802 475 ÷ 2 = 192 901 237 + 1;
  • 192 901 237 ÷ 2 = 96 450 618 + 1;
  • 96 450 618 ÷ 2 = 48 225 309 + 0;
  • 48 225 309 ÷ 2 = 24 112 654 + 1;
  • 24 112 654 ÷ 2 = 12 056 327 + 0;
  • 12 056 327 ÷ 2 = 6 028 163 + 1;
  • 6 028 163 ÷ 2 = 3 014 081 + 1;
  • 3 014 081 ÷ 2 = 1 507 040 + 1;
  • 1 507 040 ÷ 2 = 753 520 + 0;
  • 753 520 ÷ 2 = 376 760 + 0;
  • 376 760 ÷ 2 = 188 380 + 0;
  • 188 380 ÷ 2 = 94 190 + 0;
  • 94 190 ÷ 2 = 47 095 + 0;
  • 47 095 ÷ 2 = 23 547 + 1;
  • 23 547 ÷ 2 = 11 773 + 1;
  • 11 773 ÷ 2 = 5 886 + 1;
  • 5 886 ÷ 2 = 2 943 + 0;
  • 2 943 ÷ 2 = 1 471 + 1;
  • 1 471 ÷ 2 = 735 + 1;
  • 735 ÷ 2 = 367 + 1;
  • 367 ÷ 2 = 183 + 1;
  • 183 ÷ 2 = 91 + 1;
  • 91 ÷ 2 = 45 + 1;
  • 45 ÷ 2 = 22 + 1;
  • 22 ÷ 2 = 11 + 0;
  • 11 ÷ 2 = 5 + 1;
  • 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.

12 345 679 207(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

12 345 679 207 (base 10) = 10 1101 1111 1101 1100 0001 1101 0110 0111 (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)
