What are the required steps to convert base 10 decimal system
number 3 221 258 176 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;
  • 3 221 258 176 ÷ 2 = 1 610 629 088 + 0;
  • 1 610 629 088 ÷ 2 = 805 314 544 + 0;
  • 805 314 544 ÷ 2 = 402 657 272 + 0;
  • 402 657 272 ÷ 2 = 201 328 636 + 0;
  • 201 328 636 ÷ 2 = 100 664 318 + 0;
  • 100 664 318 ÷ 2 = 50 332 159 + 0;
  • 50 332 159 ÷ 2 = 25 166 079 + 1;
  • 25 166 079 ÷ 2 = 12 583 039 + 1;
  • 12 583 039 ÷ 2 = 6 291 519 + 1;
  • 6 291 519 ÷ 2 = 3 145 759 + 1;
  • 3 145 759 ÷ 2 = 1 572 879 + 1;
  • 1 572 879 ÷ 2 = 786 439 + 1;
  • 786 439 ÷ 2 = 393 219 + 1;
  • 393 219 ÷ 2 = 196 609 + 1;
  • 196 609 ÷ 2 = 98 304 + 1;
  • 98 304 ÷ 2 = 49 152 + 0;
  • 49 152 ÷ 2 = 24 576 + 0;
  • 24 576 ÷ 2 = 12 288 + 0;
  • 12 288 ÷ 2 = 6 144 + 0;
  • 6 144 ÷ 2 = 3 072 + 0;
  • 3 072 ÷ 2 = 1 536 + 0;
  • 1 536 ÷ 2 = 768 + 0;
  • 768 ÷ 2 = 384 + 0;
  • 384 ÷ 2 = 192 + 0;
  • 192 ÷ 2 = 96 + 0;
  • 96 ÷ 2 = 48 + 0;
  • 48 ÷ 2 = 24 + 0;
  • 24 ÷ 2 = 12 + 0;
  • 12 ÷ 2 = 6 + 0;
  • 6 ÷ 2 = 3 + 0;
  • 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.

3 221 258 176(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 221 258 176 (base 10) = 1100 0000 0000 0000 0111 1111 1100 0000 (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)
