What are the required steps to convert base 10 decimal system
number 4 042 322 401 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;
  • 4 042 322 401 ÷ 2 = 2 021 161 200 + 1;
  • 2 021 161 200 ÷ 2 = 1 010 580 600 + 0;
  • 1 010 580 600 ÷ 2 = 505 290 300 + 0;
  • 505 290 300 ÷ 2 = 252 645 150 + 0;
  • 252 645 150 ÷ 2 = 126 322 575 + 0;
  • 126 322 575 ÷ 2 = 63 161 287 + 1;
  • 63 161 287 ÷ 2 = 31 580 643 + 1;
  • 31 580 643 ÷ 2 = 15 790 321 + 1;
  • 15 790 321 ÷ 2 = 7 895 160 + 1;
  • 7 895 160 ÷ 2 = 3 947 580 + 0;
  • 3 947 580 ÷ 2 = 1 973 790 + 0;
  • 1 973 790 ÷ 2 = 986 895 + 0;
  • 986 895 ÷ 2 = 493 447 + 1;
  • 493 447 ÷ 2 = 246 723 + 1;
  • 246 723 ÷ 2 = 123 361 + 1;
  • 123 361 ÷ 2 = 61 680 + 1;
  • 61 680 ÷ 2 = 30 840 + 0;
  • 30 840 ÷ 2 = 15 420 + 0;
  • 15 420 ÷ 2 = 7 710 + 0;
  • 7 710 ÷ 2 = 3 855 + 0;
  • 3 855 ÷ 2 = 1 927 + 1;
  • 1 927 ÷ 2 = 963 + 1;
  • 963 ÷ 2 = 481 + 1;
  • 481 ÷ 2 = 240 + 1;
  • 240 ÷ 2 = 120 + 0;
  • 120 ÷ 2 = 60 + 0;
  • 60 ÷ 2 = 30 + 0;
  • 30 ÷ 2 = 15 + 0;
  • 15 ÷ 2 = 7 + 1;
  • 7 ÷ 2 = 3 + 1;
  • 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.

4 042 322 401(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 042 322 401 (base 10) = 1111 0000 1111 0000 1111 0001 1110 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)
