What are the required steps to convert base 10 decimal system
number 1 349 281 491 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;
  • 1 349 281 491 ÷ 2 = 674 640 745 + 1;
  • 674 640 745 ÷ 2 = 337 320 372 + 1;
  • 337 320 372 ÷ 2 = 168 660 186 + 0;
  • 168 660 186 ÷ 2 = 84 330 093 + 0;
  • 84 330 093 ÷ 2 = 42 165 046 + 1;
  • 42 165 046 ÷ 2 = 21 082 523 + 0;
  • 21 082 523 ÷ 2 = 10 541 261 + 1;
  • 10 541 261 ÷ 2 = 5 270 630 + 1;
  • 5 270 630 ÷ 2 = 2 635 315 + 0;
  • 2 635 315 ÷ 2 = 1 317 657 + 1;
  • 1 317 657 ÷ 2 = 658 828 + 1;
  • 658 828 ÷ 2 = 329 414 + 0;
  • 329 414 ÷ 2 = 164 707 + 0;
  • 164 707 ÷ 2 = 82 353 + 1;
  • 82 353 ÷ 2 = 41 176 + 1;
  • 41 176 ÷ 2 = 20 588 + 0;
  • 20 588 ÷ 2 = 10 294 + 0;
  • 10 294 ÷ 2 = 5 147 + 0;
  • 5 147 ÷ 2 = 2 573 + 1;
  • 2 573 ÷ 2 = 1 286 + 1;
  • 1 286 ÷ 2 = 643 + 0;
  • 643 ÷ 2 = 321 + 1;
  • 321 ÷ 2 = 160 + 1;
  • 160 ÷ 2 = 80 + 0;
  • 80 ÷ 2 = 40 + 0;
  • 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.

1 349 281 491(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 349 281 491 (base 10) = 101 0000 0110 1100 0110 0110 1101 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)
