What are the required steps to convert base 10 decimal system
number 6 466 867 599 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;
  • 6 466 867 599 ÷ 2 = 3 233 433 799 + 1;
  • 3 233 433 799 ÷ 2 = 1 616 716 899 + 1;
  • 1 616 716 899 ÷ 2 = 808 358 449 + 1;
  • 808 358 449 ÷ 2 = 404 179 224 + 1;
  • 404 179 224 ÷ 2 = 202 089 612 + 0;
  • 202 089 612 ÷ 2 = 101 044 806 + 0;
  • 101 044 806 ÷ 2 = 50 522 403 + 0;
  • 50 522 403 ÷ 2 = 25 261 201 + 1;
  • 25 261 201 ÷ 2 = 12 630 600 + 1;
  • 12 630 600 ÷ 2 = 6 315 300 + 0;
  • 6 315 300 ÷ 2 = 3 157 650 + 0;
  • 3 157 650 ÷ 2 = 1 578 825 + 0;
  • 1 578 825 ÷ 2 = 789 412 + 1;
  • 789 412 ÷ 2 = 394 706 + 0;
  • 394 706 ÷ 2 = 197 353 + 0;
  • 197 353 ÷ 2 = 98 676 + 1;
  • 98 676 ÷ 2 = 49 338 + 0;
  • 49 338 ÷ 2 = 24 669 + 0;
  • 24 669 ÷ 2 = 12 334 + 1;
  • 12 334 ÷ 2 = 6 167 + 0;
  • 6 167 ÷ 2 = 3 083 + 1;
  • 3 083 ÷ 2 = 1 541 + 1;
  • 1 541 ÷ 2 = 770 + 1;
  • 770 ÷ 2 = 385 + 0;
  • 385 ÷ 2 = 192 + 1;
  • 192 ÷ 2 = 96 + 0;
  • 96 ÷ 2 = 48 + 0;
  • 48 ÷ 2 = 24 + 0;
  • 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.

6 466 867 599(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

6 466 867 599 (base 10) = 1 1000 0001 0111 0100 1001 0001 1000 1111 (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)
