What are the required steps to convert base 10 decimal system
number 7 499 296 521 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;
  • 7 499 296 521 ÷ 2 = 3 749 648 260 + 1;
  • 3 749 648 260 ÷ 2 = 1 874 824 130 + 0;
  • 1 874 824 130 ÷ 2 = 937 412 065 + 0;
  • 937 412 065 ÷ 2 = 468 706 032 + 1;
  • 468 706 032 ÷ 2 = 234 353 016 + 0;
  • 234 353 016 ÷ 2 = 117 176 508 + 0;
  • 117 176 508 ÷ 2 = 58 588 254 + 0;
  • 58 588 254 ÷ 2 = 29 294 127 + 0;
  • 29 294 127 ÷ 2 = 14 647 063 + 1;
  • 14 647 063 ÷ 2 = 7 323 531 + 1;
  • 7 323 531 ÷ 2 = 3 661 765 + 1;
  • 3 661 765 ÷ 2 = 1 830 882 + 1;
  • 1 830 882 ÷ 2 = 915 441 + 0;
  • 915 441 ÷ 2 = 457 720 + 1;
  • 457 720 ÷ 2 = 228 860 + 0;
  • 228 860 ÷ 2 = 114 430 + 0;
  • 114 430 ÷ 2 = 57 215 + 0;
  • 57 215 ÷ 2 = 28 607 + 1;
  • 28 607 ÷ 2 = 14 303 + 1;
  • 14 303 ÷ 2 = 7 151 + 1;
  • 7 151 ÷ 2 = 3 575 + 1;
  • 3 575 ÷ 2 = 1 787 + 1;
  • 1 787 ÷ 2 = 893 + 1;
  • 893 ÷ 2 = 446 + 1;
  • 446 ÷ 2 = 223 + 0;
  • 223 ÷ 2 = 111 + 1;
  • 111 ÷ 2 = 55 + 1;
  • 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 number:

Take all the remainders starting from the bottom of the list constructed above.

7 499 296 521(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

7 499 296 521 (base 10) = 1 1011 1110 1111 1110 0010 1111 0000 1001 (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)
