What are the required steps to convert base 10 decimal system
number 1 615 070 242 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;
  • 1 615 070 242 ÷ 2 = 807 535 121 + 0;
  • 807 535 121 ÷ 2 = 403 767 560 + 1;
  • 403 767 560 ÷ 2 = 201 883 780 + 0;
  • 201 883 780 ÷ 2 = 100 941 890 + 0;
  • 100 941 890 ÷ 2 = 50 470 945 + 0;
  • 50 470 945 ÷ 2 = 25 235 472 + 1;
  • 25 235 472 ÷ 2 = 12 617 736 + 0;
  • 12 617 736 ÷ 2 = 6 308 868 + 0;
  • 6 308 868 ÷ 2 = 3 154 434 + 0;
  • 3 154 434 ÷ 2 = 1 577 217 + 0;
  • 1 577 217 ÷ 2 = 788 608 + 1;
  • 788 608 ÷ 2 = 394 304 + 0;
  • 394 304 ÷ 2 = 197 152 + 0;
  • 197 152 ÷ 2 = 98 576 + 0;
  • 98 576 ÷ 2 = 49 288 + 0;
  • 49 288 ÷ 2 = 24 644 + 0;
  • 24 644 ÷ 2 = 12 322 + 0;
  • 12 322 ÷ 2 = 6 161 + 0;
  • 6 161 ÷ 2 = 3 080 + 1;
  • 3 080 ÷ 2 = 1 540 + 0;
  • 1 540 ÷ 2 = 770 + 0;
  • 770 ÷ 2 = 385 + 0;
  • 385 ÷ 2 = 192 + 1;
  • 192 ÷ 2 = 96 + 0;
  • 96 ÷ 2 = 48 + 0;
  • 48 ÷ 2 = 24 + 0;
  • 24 ÷ 2 = 12 + 0;
  • 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.

1 615 070 242(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 615 070 242 (base 10) = 110 0000 0100 0100 0000 0100 0010 0010 (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)
