What are the required steps to convert base 10 decimal system
number 3 325 909 143 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;
  • 3 325 909 143 ÷ 2 = 1 662 954 571 + 1;
  • 1 662 954 571 ÷ 2 = 831 477 285 + 1;
  • 831 477 285 ÷ 2 = 415 738 642 + 1;
  • 415 738 642 ÷ 2 = 207 869 321 + 0;
  • 207 869 321 ÷ 2 = 103 934 660 + 1;
  • 103 934 660 ÷ 2 = 51 967 330 + 0;
  • 51 967 330 ÷ 2 = 25 983 665 + 0;
  • 25 983 665 ÷ 2 = 12 991 832 + 1;
  • 12 991 832 ÷ 2 = 6 495 916 + 0;
  • 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.

3 325 909 143(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 325 909 143 (base 10) = 1100 0110 0011 1101 0101 1000 1001 0111 (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)
