See below how to convert 10 000 000 018(10), the unsigned base 10 decimal system number to base 2 binary equivalent

What are the required steps to convert base 10 decimal system
number 10 000 000 018 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;
  • 10 000 000 018 ÷ 2 = 5 000 000 009 + 0;
  • 5 000 000 009 ÷ 2 = 2 500 000 004 + 1;
  • 2 500 000 004 ÷ 2 = 1 250 000 002 + 0;
  • 1 250 000 002 ÷ 2 = 625 000 001 + 0;
  • 625 000 001 ÷ 2 = 312 500 000 + 1;
  • 312 500 000 ÷ 2 = 156 250 000 + 0;
  • 156 250 000 ÷ 2 = 78 125 000 + 0;
  • 78 125 000 ÷ 2 = 39 062 500 + 0;
  • 39 062 500 ÷ 2 = 19 531 250 + 0;
  • 19 531 250 ÷ 2 = 9 765 625 + 0;
  • 9 765 625 ÷ 2 = 4 882 812 + 1;
  • 4 882 812 ÷ 2 = 2 441 406 + 0;
  • 2 441 406 ÷ 2 = 1 220 703 + 0;
  • 1 220 703 ÷ 2 = 610 351 + 1;
  • 610 351 ÷ 2 = 305 175 + 1;
  • 305 175 ÷ 2 = 152 587 + 1;
  • 152 587 ÷ 2 = 76 293 + 1;
  • 76 293 ÷ 2 = 38 146 + 1;
  • 38 146 ÷ 2 = 19 073 + 0;
  • 19 073 ÷ 2 = 9 536 + 1;
  • 9 536 ÷ 2 = 4 768 + 0;
  • 4 768 ÷ 2 = 2 384 + 0;
  • 2 384 ÷ 2 = 1 192 + 0;
  • 1 192 ÷ 2 = 596 + 0;
  • 596 ÷ 2 = 298 + 0;
  • 298 ÷ 2 = 149 + 0;
  • 149 ÷ 2 = 74 + 1;
  • 74 ÷ 2 = 37 + 0;
  • 37 ÷ 2 = 18 + 1;
  • 18 ÷ 2 = 9 + 0;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 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.

10 000 000 018(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

10 000 000 018 (base 10) = 10 0101 0100 0000 1011 1110 0100 0001 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)
