What are the required steps to convert base 10 decimal system
number 11 111 000 385 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;
  • 11 111 000 385 ÷ 2 = 5 555 500 192 + 1;
  • 5 555 500 192 ÷ 2 = 2 777 750 096 + 0;
  • 2 777 750 096 ÷ 2 = 1 388 875 048 + 0;
  • 1 388 875 048 ÷ 2 = 694 437 524 + 0;
  • 694 437 524 ÷ 2 = 347 218 762 + 0;
  • 347 218 762 ÷ 2 = 173 609 381 + 0;
  • 173 609 381 ÷ 2 = 86 804 690 + 1;
  • 86 804 690 ÷ 2 = 43 402 345 + 0;
  • 43 402 345 ÷ 2 = 21 701 172 + 1;
  • 21 701 172 ÷ 2 = 10 850 586 + 0;
  • 10 850 586 ÷ 2 = 5 425 293 + 0;
  • 5 425 293 ÷ 2 = 2 712 646 + 1;
  • 2 712 646 ÷ 2 = 1 356 323 + 0;
  • 1 356 323 ÷ 2 = 678 161 + 1;
  • 678 161 ÷ 2 = 339 080 + 1;
  • 339 080 ÷ 2 = 169 540 + 0;
  • 169 540 ÷ 2 = 84 770 + 0;
  • 84 770 ÷ 2 = 42 385 + 0;
  • 42 385 ÷ 2 = 21 192 + 1;
  • 21 192 ÷ 2 = 10 596 + 0;
  • 10 596 ÷ 2 = 5 298 + 0;
  • 5 298 ÷ 2 = 2 649 + 0;
  • 2 649 ÷ 2 = 1 324 + 1;
  • 1 324 ÷ 2 = 662 + 0;
  • 662 ÷ 2 = 331 + 0;
  • 331 ÷ 2 = 165 + 1;
  • 165 ÷ 2 = 82 + 1;
  • 82 ÷ 2 = 41 + 0;
  • 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.

11 111 000 385(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

11 111 000 385 (base 10) = 10 1001 0110 0100 0100 0110 1001 0100 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)
