What are the required steps to convert base 10 decimal system
number 3 678 560 898 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;
  • 3 678 560 898 ÷ 2 = 1 839 280 449 + 0;
  • 1 839 280 449 ÷ 2 = 919 640 224 + 1;
  • 919 640 224 ÷ 2 = 459 820 112 + 0;
  • 459 820 112 ÷ 2 = 229 910 056 + 0;
  • 229 910 056 ÷ 2 = 114 955 028 + 0;
  • 114 955 028 ÷ 2 = 57 477 514 + 0;
  • 57 477 514 ÷ 2 = 28 738 757 + 0;
  • 28 738 757 ÷ 2 = 14 369 378 + 1;
  • 14 369 378 ÷ 2 = 7 184 689 + 0;
  • 7 184 689 ÷ 2 = 3 592 344 + 1;
  • 3 592 344 ÷ 2 = 1 796 172 + 0;
  • 1 796 172 ÷ 2 = 898 086 + 0;
  • 898 086 ÷ 2 = 449 043 + 0;
  • 449 043 ÷ 2 = 224 521 + 1;
  • 224 521 ÷ 2 = 112 260 + 1;
  • 112 260 ÷ 2 = 56 130 + 0;
  • 56 130 ÷ 2 = 28 065 + 0;
  • 28 065 ÷ 2 = 14 032 + 1;
  • 14 032 ÷ 2 = 7 016 + 0;
  • 7 016 ÷ 2 = 3 508 + 0;
  • 3 508 ÷ 2 = 1 754 + 0;
  • 1 754 ÷ 2 = 877 + 0;
  • 877 ÷ 2 = 438 + 1;
  • 438 ÷ 2 = 219 + 0;
  • 219 ÷ 2 = 109 + 1;
  • 109 ÷ 2 = 54 + 1;
  • 54 ÷ 2 = 27 + 0;
  • 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 number:

Take all the remainders starting from the bottom of the list constructed above.

3 678 560 898(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

3 678 560 898 (base 10) = 1101 1011 0100 0010 0110 0010 1000 0010 (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)
