What are the required steps to convert base 10 decimal system
number 2 791 728 931 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;
  • 2 791 728 931 ÷ 2 = 1 395 864 465 + 1;
  • 1 395 864 465 ÷ 2 = 697 932 232 + 1;
  • 697 932 232 ÷ 2 = 348 966 116 + 0;
  • 348 966 116 ÷ 2 = 174 483 058 + 0;
  • 174 483 058 ÷ 2 = 87 241 529 + 0;
  • 87 241 529 ÷ 2 = 43 620 764 + 1;
  • 43 620 764 ÷ 2 = 21 810 382 + 0;
  • 21 810 382 ÷ 2 = 10 905 191 + 0;
  • 10 905 191 ÷ 2 = 5 452 595 + 1;
  • 5 452 595 ÷ 2 = 2 726 297 + 1;
  • 2 726 297 ÷ 2 = 1 363 148 + 1;
  • 1 363 148 ÷ 2 = 681 574 + 0;
  • 681 574 ÷ 2 = 340 787 + 0;
  • 340 787 ÷ 2 = 170 393 + 1;
  • 170 393 ÷ 2 = 85 196 + 1;
  • 85 196 ÷ 2 = 42 598 + 0;
  • 42 598 ÷ 2 = 21 299 + 0;
  • 21 299 ÷ 2 = 10 649 + 1;
  • 10 649 ÷ 2 = 5 324 + 1;
  • 5 324 ÷ 2 = 2 662 + 0;
  • 2 662 ÷ 2 = 1 331 + 0;
  • 1 331 ÷ 2 = 665 + 1;
  • 665 ÷ 2 = 332 + 1;
  • 332 ÷ 2 = 166 + 0;
  • 166 ÷ 2 = 83 + 0;
  • 83 ÷ 2 = 41 + 1;
  • 41 ÷ 2 = 20 + 1;
  • 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.

2 791 728 931(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 791 728 931 (base 10) = 1010 0110 0110 0110 0110 0111 0010 0011 (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)
