What are the required steps to convert base 10 decimal system
number 1 648 625 889 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;
  • 1 648 625 889 ÷ 2 = 824 312 944 + 1;
  • 824 312 944 ÷ 2 = 412 156 472 + 0;
  • 412 156 472 ÷ 2 = 206 078 236 + 0;
  • 206 078 236 ÷ 2 = 103 039 118 + 0;
  • 103 039 118 ÷ 2 = 51 519 559 + 0;
  • 51 519 559 ÷ 2 = 25 759 779 + 1;
  • 25 759 779 ÷ 2 = 12 879 889 + 1;
  • 12 879 889 ÷ 2 = 6 439 944 + 1;
  • 6 439 944 ÷ 2 = 3 219 972 + 0;
  • 3 219 972 ÷ 2 = 1 609 986 + 0;
  • 1 609 986 ÷ 2 = 804 993 + 0;
  • 804 993 ÷ 2 = 402 496 + 1;
  • 402 496 ÷ 2 = 201 248 + 0;
  • 201 248 ÷ 2 = 100 624 + 0;
  • 100 624 ÷ 2 = 50 312 + 0;
  • 50 312 ÷ 2 = 25 156 + 0;
  • 25 156 ÷ 2 = 12 578 + 0;
  • 12 578 ÷ 2 = 6 289 + 0;
  • 6 289 ÷ 2 = 3 144 + 1;
  • 3 144 ÷ 2 = 1 572 + 0;
  • 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.

1 648 625 889(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 648 625 889 (base 10) = 110 0010 0100 0100 0000 1000 1110 0001 (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)
