  • 6 413 462 ÷ 2 = 3 206 731 + 0;
  • 3 206 731 ÷ 2 = 1 603 365 + 1;
  • 1 603 365 ÷ 2 = 801 682 + 1;
  • 801 682 ÷ 2 = 400 841 + 0;
  • 400 841 ÷ 2 = 200 420 + 1;
  • 200 420 ÷ 2 = 100 210 + 0;
  • 100 210 ÷ 2 = 50 105 + 0;
  • 50 105 ÷ 2 = 25 052 + 1;
  • 25 052 ÷ 2 = 12 526 + 0;
  • 12 526 ÷ 2 = 6 263 + 0;
  • 6 263 ÷ 2 = 3 131 + 1;
  • 3 131 ÷ 2 = 1 565 + 1;
  • 1 565 ÷ 2 = 782 + 1;
  • 782 ÷ 2 = 391 + 0;
  • 391 ÷ 2 = 195 + 1;
  • 195 ÷ 2 = 97 + 1;
  • 97 ÷ 2 = 48 + 1;
  • 48 ÷ 2 = 24 + 0;
  • 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.


Number 102 615 394(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):

102 615 394(10) = 110 0001 1101 1100 1001 0110 0010(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 ten to base two

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)
