What are the required steps to convert base 10 decimal system
number 2 415 918 999 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;
  • 2 415 918 999 ÷ 2 = 1 207 959 499 + 1;
  • 1 207 959 499 ÷ 2 = 603 979 749 + 1;
  • 603 979 749 ÷ 2 = 301 989 874 + 1;
  • 301 989 874 ÷ 2 = 150 994 937 + 0;
  • 150 994 937 ÷ 2 = 75 497 468 + 1;
  • 75 497 468 ÷ 2 = 37 748 734 + 0;
  • 37 748 734 ÷ 2 = 18 874 367 + 0;
  • 18 874 367 ÷ 2 = 9 437 183 + 1;
  • 9 437 183 ÷ 2 = 4 718 591 + 1;
  • 4 718 591 ÷ 2 = 2 359 295 + 1;
  • 2 359 295 ÷ 2 = 1 179 647 + 1;
  • 1 179 647 ÷ 2 = 589 823 + 1;
  • 589 823 ÷ 2 = 294 911 + 1;
  • 294 911 ÷ 2 = 147 455 + 1;
  • 147 455 ÷ 2 = 73 727 + 1;
  • 73 727 ÷ 2 = 36 863 + 1;
  • 36 863 ÷ 2 = 18 431 + 1;
  • 18 431 ÷ 2 = 9 215 + 1;
  • 9 215 ÷ 2 = 4 607 + 1;
  • 4 607 ÷ 2 = 2 303 + 1;
  • 2 303 ÷ 2 = 1 151 + 1;
  • 1 151 ÷ 2 = 575 + 1;
  • 575 ÷ 2 = 287 + 1;
  • 287 ÷ 2 = 143 + 1;
  • 143 ÷ 2 = 71 + 1;
  • 71 ÷ 2 = 35 + 1;
  • 35 ÷ 2 = 17 + 1;
  • 17 ÷ 2 = 8 + 1;
  • 8 ÷ 2 = 4 + 0;
  • 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.

2 415 918 999(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 415 918 999 (base 10) = 1000 1111 1111 1111 1111 1111 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)
