What are the required steps to convert base 10 decimal system
number 2 345 678 842 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;
  • 2 345 678 842 ÷ 2 = 1 172 839 421 + 0;
  • 1 172 839 421 ÷ 2 = 586 419 710 + 1;
  • 586 419 710 ÷ 2 = 293 209 855 + 0;
  • 293 209 855 ÷ 2 = 146 604 927 + 1;
  • 146 604 927 ÷ 2 = 73 302 463 + 1;
  • 73 302 463 ÷ 2 = 36 651 231 + 1;
  • 36 651 231 ÷ 2 = 18 325 615 + 1;
  • 18 325 615 ÷ 2 = 9 162 807 + 1;
  • 9 162 807 ÷ 2 = 4 581 403 + 1;
  • 4 581 403 ÷ 2 = 2 290 701 + 1;
  • 2 290 701 ÷ 2 = 1 145 350 + 1;
  • 1 145 350 ÷ 2 = 572 675 + 0;
  • 572 675 ÷ 2 = 286 337 + 1;
  • 286 337 ÷ 2 = 143 168 + 1;
  • 143 168 ÷ 2 = 71 584 + 0;
  • 71 584 ÷ 2 = 35 792 + 0;
  • 35 792 ÷ 2 = 17 896 + 0;
  • 17 896 ÷ 2 = 8 948 + 0;
  • 8 948 ÷ 2 = 4 474 + 0;
  • 4 474 ÷ 2 = 2 237 + 0;
  • 2 237 ÷ 2 = 1 118 + 1;
  • 1 118 ÷ 2 = 559 + 0;
  • 559 ÷ 2 = 279 + 1;
  • 279 ÷ 2 = 139 + 1;
  • 139 ÷ 2 = 69 + 1;
  • 69 ÷ 2 = 34 + 1;
  • 34 ÷ 2 = 17 + 0;
  • 17 ÷ 2 = 8 + 1;
  • 8 ÷ 2 = 4 + 0;
  • 4 ÷ 2 = 2 + 0;
  • 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.

2 345 678 842(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 345 678 842 (base 10) = 1000 1011 1101 0000 0011 0111 1111 1010 (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)
