We're dividing 873009 by 2 
Our goal is to divide 873009 by 2.

Advancing to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Advancing to step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 6 away from 7, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Step 3:
2 goes into 13 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we subtract 12 from 13, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 4:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4365.0
The remainder is 0 after subtracting 10 from 10.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Moving on to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43650.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Advancing to step 6:
9 divided by 2 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 436504.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 436504.5
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 436504.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 436504.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 436504.5, and the remainder is 0.0.
