What are the required steps to convert base 10 decimal system
number 33 333 333 321 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;
  • 33 333 333 321 ÷ 2 = 16 666 666 660 + 1;
  • 16 666 666 660 ÷ 2 = 8 333 333 330 + 0;
  • 8 333 333 330 ÷ 2 = 4 166 666 665 + 0;
  • 4 166 666 665 ÷ 2 = 2 083 333 332 + 1;
  • 2 083 333 332 ÷ 2 = 1 041 666 666 + 0;
  • 1 041 666 666 ÷ 2 = 520 833 333 + 0;
  • 520 833 333 ÷ 2 = 260 416 666 + 1;
  • 260 416 666 ÷ 2 = 130 208 333 + 0;
  • 130 208 333 ÷ 2 = 65 104 166 + 1;
  • 65 104 166 ÷ 2 = 32 552 083 + 0;
  • 32 552 083 ÷ 2 = 16 276 041 + 1;
  • 16 276 041 ÷ 2 = 8 138 020 + 1;
  • 8 138 020 ÷ 2 = 4 069 010 + 0;
  • 4 069 010 ÷ 2 = 2 034 505 + 0;
  • 2 034 505 ÷ 2 = 1 017 252 + 1;
  • 1 017 252 ÷ 2 = 508 626 + 0;
  • 508 626 ÷ 2 = 254 313 + 0;
  • 254 313 ÷ 2 = 127 156 + 1;
  • 127 156 ÷ 2 = 63 578 + 0;
  • 63 578 ÷ 2 = 31 789 + 0;
  • 31 789 ÷ 2 = 15 894 + 1;
  • 15 894 ÷ 2 = 7 947 + 0;
  • 7 947 ÷ 2 = 3 973 + 1;
  • 3 973 ÷ 2 = 1 986 + 1;
  • 1 986 ÷ 2 = 993 + 0;
  • 993 ÷ 2 = 496 + 1;
  • 496 ÷ 2 = 248 + 0;
  • 248 ÷ 2 = 124 + 0;
  • 124 ÷ 2 = 62 + 0;
  • 62 ÷ 2 = 31 + 0;
  • 31 ÷ 2 = 15 + 1;
  • 15 ÷ 2 = 7 + 1;
  • 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.

33 333 333 321(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

33 333 333 321 (base 10) = 111 1100 0010 1101 0010 0100 1101 0100 1001 (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)
