Base Ten to Base Two: Unsigned Number 24 121 953 Converted and Written in Base Two. Natural Number (Positive Integer, No Sign) Converted From Decimal System to Binary Code

Base ten unsigned number 24 121 953(10) converted and written as a base two binary code

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when getting a quotient that is equal to zero.


  • division = quotient + remainder;
  • 24 121 953 ÷ 2 = 12 060 976 + 1;
  • 12 060 976 ÷ 2 = 6 030 488 + 0;
  • 6 030 488 ÷ 2 = 3 015 244 + 0;
  • 3 015 244 ÷ 2 = 1 507 622 + 0;
  • 1 507 622 ÷ 2 = 753 811 + 0;
  • 753 811 ÷ 2 = 376 905 + 1;
  • 376 905 ÷ 2 = 188 452 + 1;
  • 188 452 ÷ 2 = 94 226 + 0;
  • 94 226 ÷ 2 = 47 113 + 0;
  • 47 113 ÷ 2 = 23 556 + 1;
  • 23 556 ÷ 2 = 11 778 + 0;
  • 11 778 ÷ 2 = 5 889 + 0;
  • 5 889 ÷ 2 = 2 944 + 1;
  • 2 944 ÷ 2 = 1 472 + 0;
  • 1 472 ÷ 2 = 736 + 0;
  • 736 ÷ 2 = 368 + 0;
  • 368 ÷ 2 = 184 + 0;
  • 184 ÷ 2 = 92 + 0;
  • 92 ÷ 2 = 46 + 0;
  • 46 ÷ 2 = 23 + 0;
  • 23 ÷ 2 = 11 + 1;
  • 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.

Number 24 121 953(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):

24 121 953(10) = 1 0111 0000 0001 0010 0110 0001(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 ten to base two

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)
