What are the required steps to convert base 10 decimal system
number 1 644 169 249 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;
  • 1 644 169 249 ÷ 2 = 822 084 624 + 1;
  • 822 084 624 ÷ 2 = 411 042 312 + 0;
  • 411 042 312 ÷ 2 = 205 521 156 + 0;
  • 205 521 156 ÷ 2 = 102 760 578 + 0;
  • 102 760 578 ÷ 2 = 51 380 289 + 0;
  • 51 380 289 ÷ 2 = 25 690 144 + 1;
  • 25 690 144 ÷ 2 = 12 845 072 + 0;
  • 12 845 072 ÷ 2 = 6 422 536 + 0;
  • 6 422 536 ÷ 2 = 3 211 268 + 0;
  • 3 211 268 ÷ 2 = 1 605 634 + 0;
  • 1 605 634 ÷ 2 = 802 817 + 0;
  • 802 817 ÷ 2 = 401 408 + 1;
  • 401 408 ÷ 2 = 200 704 + 0;
  • 200 704 ÷ 2 = 100 352 + 0;
  • 100 352 ÷ 2 = 50 176 + 0;
  • 50 176 ÷ 2 = 25 088 + 0;
  • 25 088 ÷ 2 = 12 544 + 0;
  • 12 544 ÷ 2 = 6 272 + 0;
  • 6 272 ÷ 2 = 3 136 + 0;
  • 3 136 ÷ 2 = 1 568 + 0;
  • 1 568 ÷ 2 = 784 + 0;
  • 784 ÷ 2 = 392 + 0;
  • 392 ÷ 2 = 196 + 0;
  • 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.

1 644 169 249(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 644 169 249 (base 10) = 110 0010 0000 0000 0000 1000 0010 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)
