What are the required steps to convert base 10 decimal system
number 1 517 123 457 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;
  • 1 517 123 457 ÷ 2 = 758 561 728 + 1;
  • 758 561 728 ÷ 2 = 379 280 864 + 0;
  • 379 280 864 ÷ 2 = 189 640 432 + 0;
  • 189 640 432 ÷ 2 = 94 820 216 + 0;
  • 94 820 216 ÷ 2 = 47 410 108 + 0;
  • 47 410 108 ÷ 2 = 23 705 054 + 0;
  • 23 705 054 ÷ 2 = 11 852 527 + 0;
  • 11 852 527 ÷ 2 = 5 926 263 + 1;
  • 5 926 263 ÷ 2 = 2 963 131 + 1;
  • 2 963 131 ÷ 2 = 1 481 565 + 1;
  • 1 481 565 ÷ 2 = 740 782 + 1;
  • 740 782 ÷ 2 = 370 391 + 0;
  • 370 391 ÷ 2 = 185 195 + 1;
  • 185 195 ÷ 2 = 92 597 + 1;
  • 92 597 ÷ 2 = 46 298 + 1;
  • 46 298 ÷ 2 = 23 149 + 0;
  • 23 149 ÷ 2 = 11 574 + 1;
  • 11 574 ÷ 2 = 5 787 + 0;
  • 5 787 ÷ 2 = 2 893 + 1;
  • 2 893 ÷ 2 = 1 446 + 1;
  • 1 446 ÷ 2 = 723 + 0;
  • 723 ÷ 2 = 361 + 1;
  • 361 ÷ 2 = 180 + 1;
  • 180 ÷ 2 = 90 + 0;
  • 90 ÷ 2 = 45 + 0;
  • 45 ÷ 2 = 22 + 1;
  • 22 ÷ 2 = 11 + 0;
  • 11 ÷ 2 = 5 + 1;
  • 5 ÷ 2 = 2 + 1;
  • 2 ÷ 2 = 1 + 0;
  • 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.

1 517 123 457(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 517 123 457 (base 10) = 101 1010 0110 1101 0111 0111 1000 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)
