What are the required steps to convert base 10 decimal system
number 3 825 173 461 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;
  • 3 825 173 461 ÷ 2 = 1 912 586 730 + 1;
  • 1 912 586 730 ÷ 2 = 956 293 365 + 0;
  • 956 293 365 ÷ 2 = 478 146 682 + 1;
  • 478 146 682 ÷ 2 = 239 073 341 + 0;
  • 239 073 341 ÷ 2 = 119 536 670 + 1;
  • 119 536 670 ÷ 2 = 59 768 335 + 0;
  • 59 768 335 ÷ 2 = 29 884 167 + 1;
  • 29 884 167 ÷ 2 = 14 942 083 + 1;
  • 14 942 083 ÷ 2 = 7 471 041 + 1;
  • 7 471 041 ÷ 2 = 3 735 520 + 1;
  • 3 735 520 ÷ 2 = 1 867 760 + 0;
  • 1 867 760 ÷ 2 = 933 880 + 0;
  • 933 880 ÷ 2 = 466 940 + 0;
  • 466 940 ÷ 2 = 233 470 + 0;
  • 233 470 ÷ 2 = 116 735 + 0;
  • 116 735 ÷ 2 = 58 367 + 1;
  • 58 367 ÷ 2 = 29 183 + 1;
  • 29 183 ÷ 2 = 14 591 + 1;
  • 14 591 ÷ 2 = 7 295 + 1;
  • 7 295 ÷ 2 = 3 647 + 1;
  • 3 647 ÷ 2 = 1 823 + 1;
  • 1 823 ÷ 2 = 911 + 1;
  • 911 ÷ 2 = 455 + 1;
  • 455 ÷ 2 = 227 + 1;
  • 227 ÷ 2 = 113 + 1;
  • 113 ÷ 2 = 56 + 1;
  • 56 ÷ 2 = 28 + 0;
  • 28 ÷ 2 = 14 + 0;
  • 14 ÷ 2 = 7 + 0;
  • 7 ÷ 2 = 3 + 1;
  • 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.

3 825 173 461(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 825 173 461 (base 10) = 1110 0011 1111 1111 1000 0011 1101 0101 (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)
