What are the required steps to convert base 10 decimal system
number 1 648 953 720 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;
  • 1 648 953 720 ÷ 2 = 824 476 860 + 0;
  • 824 476 860 ÷ 2 = 412 238 430 + 0;
  • 412 238 430 ÷ 2 = 206 119 215 + 0;
  • 206 119 215 ÷ 2 = 103 059 607 + 1;
  • 103 059 607 ÷ 2 = 51 529 803 + 1;
  • 51 529 803 ÷ 2 = 25 764 901 + 1;
  • 25 764 901 ÷ 2 = 12 882 450 + 1;
  • 12 882 450 ÷ 2 = 6 441 225 + 0;
  • 6 441 225 ÷ 2 = 3 220 612 + 1;
  • 3 220 612 ÷ 2 = 1 610 306 + 0;
  • 1 610 306 ÷ 2 = 805 153 + 0;
  • 805 153 ÷ 2 = 402 576 + 1;
  • 402 576 ÷ 2 = 201 288 + 0;
  • 201 288 ÷ 2 = 100 644 + 0;
  • 100 644 ÷ 2 = 50 322 + 0;
  • 50 322 ÷ 2 = 25 161 + 0;
  • 25 161 ÷ 2 = 12 580 + 1;
  • 12 580 ÷ 2 = 6 290 + 0;
  • 6 290 ÷ 2 = 3 145 + 0;
  • 3 145 ÷ 2 = 1 572 + 1;
  • 1 572 ÷ 2 = 786 + 0;
  • 786 ÷ 2 = 393 + 0;
  • 393 ÷ 2 = 196 + 1;
  • 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.

1 648 953 720(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 648 953 720 (base 10) = 110 0010 0100 1001 0000 1001 0111 1000 (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)
