What are the required steps to convert base 10 decimal system
number 1 647 019 839 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;
  • 1 647 019 839 ÷ 2 = 823 509 919 + 1;
  • 823 509 919 ÷ 2 = 411 754 959 + 1;
  • 411 754 959 ÷ 2 = 205 877 479 + 1;
  • 205 877 479 ÷ 2 = 102 938 739 + 1;
  • 102 938 739 ÷ 2 = 51 469 369 + 1;
  • 51 469 369 ÷ 2 = 25 734 684 + 1;
  • 25 734 684 ÷ 2 = 12 867 342 + 0;
  • 12 867 342 ÷ 2 = 6 433 671 + 0;
  • 6 433 671 ÷ 2 = 3 216 835 + 1;
  • 3 216 835 ÷ 2 = 1 608 417 + 1;
  • 1 608 417 ÷ 2 = 804 208 + 1;
  • 804 208 ÷ 2 = 402 104 + 0;
  • 402 104 ÷ 2 = 201 052 + 0;
  • 201 052 ÷ 2 = 100 526 + 0;
  • 100 526 ÷ 2 = 50 263 + 0;
  • 50 263 ÷ 2 = 25 131 + 1;
  • 25 131 ÷ 2 = 12 565 + 1;
  • 12 565 ÷ 2 = 6 282 + 1;
  • 6 282 ÷ 2 = 3 141 + 0;
  • 3 141 ÷ 2 = 1 570 + 1;
  • 1 570 ÷ 2 = 785 + 0;
  • 785 ÷ 2 = 392 + 1;
  • 392 ÷ 2 = 196 + 0;
  • 196 ÷ 2 = 98 + 0;
  • 98 ÷ 2 = 49 + 0;
  • 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.

1 647 019 839(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 647 019 839 (base 10) = 110 0010 0010 1011 1000 0111 0011 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)
