We look at the division of 239009 by 80 
We're looking to find how many times 80 goes into 239009.

Going ahead to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 80

Advancing to step 2:
80 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 80

On to step 3:
If we divide 239 by 80, we get 2 and a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 160 from 239 to get 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 80

Step 4:
If we divide 790 by 80, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 720 from 790 leaves us with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 80

Moving on to step 5:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 298.0
The remainder is 60 after subtracting 640 from 700.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 80

Advancing to step 6:
The number 80 fits into 609 7 times, leaving a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 2987.0
The remainder is 49 after subtracting 560 from 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
If we divide 490 by 80, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2987.6
If we take 480 away from 490, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
80 goes into 100 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 2987.61
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2987.612
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2987.6125
If we subtract 400 from 400, we 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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2987.6125
If we subtract 0 from 0, we 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 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2987.6125
Subtract 0 from 0 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.

The quotient of the division is 2987.6125, and the remainder is 0.0.
