What are the required steps to convert base 10 decimal system
number 3 325 909 371 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;
  • 3 325 909 371 ÷ 2 = 1 662 954 685 + 1;
  • 1 662 954 685 ÷ 2 = 831 477 342 + 1;
  • 831 477 342 ÷ 2 = 415 738 671 + 0;
  • 415 738 671 ÷ 2 = 207 869 335 + 1;
  • 207 869 335 ÷ 2 = 103 934 667 + 1;
  • 103 934 667 ÷ 2 = 51 967 333 + 1;
  • 51 967 333 ÷ 2 = 25 983 666 + 1;
  • 25 983 666 ÷ 2 = 12 991 833 + 0;
  • 12 991 833 ÷ 2 = 6 495 916 + 1;
  • 6 495 916 ÷ 2 = 3 247 958 + 0;
  • 3 247 958 ÷ 2 = 1 623 979 + 0;
  • 1 623 979 ÷ 2 = 811 989 + 1;
  • 811 989 ÷ 2 = 405 994 + 1;
  • 405 994 ÷ 2 = 202 997 + 0;
  • 202 997 ÷ 2 = 101 498 + 1;
  • 101 498 ÷ 2 = 50 749 + 0;
  • 50 749 ÷ 2 = 25 374 + 1;
  • 25 374 ÷ 2 = 12 687 + 0;
  • 12 687 ÷ 2 = 6 343 + 1;
  • 6 343 ÷ 2 = 3 171 + 1;
  • 3 171 ÷ 2 = 1 585 + 1;
  • 1 585 ÷ 2 = 792 + 1;
  • 792 ÷ 2 = 396 + 0;
  • 396 ÷ 2 = 198 + 0;
  • 198 ÷ 2 = 99 + 0;
  • 99 ÷ 2 = 49 + 1;
  • 49 ÷ 2 = 24 + 1;
  • 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.

3 325 909 371(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 325 909 371 (base 10) = 1100 0110 0011 1101 0101 1001 0111 1011 (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)
