What are the required steps to convert base 10 decimal system
number 1 698 334 251 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;
  • 1 698 334 251 ÷ 2 = 849 167 125 + 1;
  • 849 167 125 ÷ 2 = 424 583 562 + 1;
  • 424 583 562 ÷ 2 = 212 291 781 + 0;
  • 212 291 781 ÷ 2 = 106 145 890 + 1;
  • 106 145 890 ÷ 2 = 53 072 945 + 0;
  • 53 072 945 ÷ 2 = 26 536 472 + 1;
  • 26 536 472 ÷ 2 = 13 268 236 + 0;
  • 13 268 236 ÷ 2 = 6 634 118 + 0;
  • 6 634 118 ÷ 2 = 3 317 059 + 0;
  • 3 317 059 ÷ 2 = 1 658 529 + 1;
  • 1 658 529 ÷ 2 = 829 264 + 1;
  • 829 264 ÷ 2 = 414 632 + 0;
  • 414 632 ÷ 2 = 207 316 + 0;
  • 207 316 ÷ 2 = 103 658 + 0;
  • 103 658 ÷ 2 = 51 829 + 0;
  • 51 829 ÷ 2 = 25 914 + 1;
  • 25 914 ÷ 2 = 12 957 + 0;
  • 12 957 ÷ 2 = 6 478 + 1;
  • 6 478 ÷ 2 = 3 239 + 0;
  • 3 239 ÷ 2 = 1 619 + 1;
  • 1 619 ÷ 2 = 809 + 1;
  • 809 ÷ 2 = 404 + 1;
  • 404 ÷ 2 = 202 + 0;
  • 202 ÷ 2 = 101 + 0;
  • 101 ÷ 2 = 50 + 1;
  • 50 ÷ 2 = 25 + 0;
  • 25 ÷ 2 = 12 + 1;
  • 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.

1 698 334 251(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 698 334 251 (base 10) = 110 0101 0011 1010 1000 0110 0010 1011 (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)
