What are the required steps to convert base 10 decimal system
number 1 361 335 699 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;
  • 1 361 335 699 ÷ 2 = 680 667 849 + 1;
  • 680 667 849 ÷ 2 = 340 333 924 + 1;
  • 340 333 924 ÷ 2 = 170 166 962 + 0;
  • 170 166 962 ÷ 2 = 85 083 481 + 0;
  • 85 083 481 ÷ 2 = 42 541 740 + 1;
  • 42 541 740 ÷ 2 = 21 270 870 + 0;
  • 21 270 870 ÷ 2 = 10 635 435 + 0;
  • 10 635 435 ÷ 2 = 5 317 717 + 1;
  • 5 317 717 ÷ 2 = 2 658 858 + 1;
  • 2 658 858 ÷ 2 = 1 329 429 + 0;
  • 1 329 429 ÷ 2 = 664 714 + 1;
  • 664 714 ÷ 2 = 332 357 + 0;
  • 332 357 ÷ 2 = 166 178 + 1;
  • 166 178 ÷ 2 = 83 089 + 0;
  • 83 089 ÷ 2 = 41 544 + 1;
  • 41 544 ÷ 2 = 20 772 + 0;
  • 20 772 ÷ 2 = 10 386 + 0;
  • 10 386 ÷ 2 = 5 193 + 0;
  • 5 193 ÷ 2 = 2 596 + 1;
  • 2 596 ÷ 2 = 1 298 + 0;
  • 1 298 ÷ 2 = 649 + 0;
  • 649 ÷ 2 = 324 + 1;
  • 324 ÷ 2 = 162 + 0;
  • 162 ÷ 2 = 81 + 0;
  • 81 ÷ 2 = 40 + 1;
  • 40 ÷ 2 = 20 + 0;
  • 20 ÷ 2 = 10 + 0;
  • 10 ÷ 2 = 5 + 0;
  • 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.

1 361 335 699(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 361 335 699 (base 10) = 101 0001 0010 0100 0101 0101 1001 0011 (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)
