What are the required steps to convert base 10 decimal system
number 1 408 591 345 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;
  • 1 408 591 345 ÷ 2 = 704 295 672 + 1;
  • 704 295 672 ÷ 2 = 352 147 836 + 0;
  • 352 147 836 ÷ 2 = 176 073 918 + 0;
  • 176 073 918 ÷ 2 = 88 036 959 + 0;
  • 88 036 959 ÷ 2 = 44 018 479 + 1;
  • 44 018 479 ÷ 2 = 22 009 239 + 1;
  • 22 009 239 ÷ 2 = 11 004 619 + 1;
  • 11 004 619 ÷ 2 = 5 502 309 + 1;
  • 5 502 309 ÷ 2 = 2 751 154 + 1;
  • 2 751 154 ÷ 2 = 1 375 577 + 0;
  • 1 375 577 ÷ 2 = 687 788 + 1;
  • 687 788 ÷ 2 = 343 894 + 0;
  • 343 894 ÷ 2 = 171 947 + 0;
  • 171 947 ÷ 2 = 85 973 + 1;
  • 85 973 ÷ 2 = 42 986 + 1;
  • 42 986 ÷ 2 = 21 493 + 0;
  • 21 493 ÷ 2 = 10 746 + 1;
  • 10 746 ÷ 2 = 5 373 + 0;
  • 5 373 ÷ 2 = 2 686 + 1;
  • 2 686 ÷ 2 = 1 343 + 0;
  • 1 343 ÷ 2 = 671 + 1;
  • 671 ÷ 2 = 335 + 1;
  • 335 ÷ 2 = 167 + 1;
  • 167 ÷ 2 = 83 + 1;
  • 83 ÷ 2 = 41 + 1;
  • 41 ÷ 2 = 20 + 1;
  • 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.

1 408 591 345(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 408 591 345 (base 10) = 101 0011 1111 0101 0110 0101 1111 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)
