We're dividing 28722407 by 809 
We want to divide 28722407 by 809.

Let's proceed to step 1:
When dividing 2 by 809, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 809

Let's proceed to step 2:
When dividing 28 by 809, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 809

On to step 3:
If we divide 287 by 809, we get 0 and a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 287, we get 287.
Append the next digit (2) from the dividend to 287 and continue with: 2872 / 809

Going ahead to step 4:
809 can be fit into 2872 3 times, resulting in a remainder of 445.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2427 from 2872 and we're left with 445.
Take the next digit (2) from the dividend and append it to 445, then repeat: 4452 / 809

On to step 5:
809 goes into 4452 5 times with a remainder of 407.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 4045 from 4452, we get 407.
Grab the next digit (4) from the dividend, add it to 407, then carry on: 4074 / 809

On to step 6:
809 can be fit into 4074 5 times, resulting in a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 355.0
Subtract 4045 from 4074 to get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 809

Step 7:
The number 809 fits into 290 0 times, leaving a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 3550.0
Subtract 0 from 290 to get 290.
Include the next digit (7) from the dividend after 290, then repeat: 2907 / 809

Step 8:
When dividing 2907 by 809, we get 3 with a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 35503.0
Deduct 2427 from 2907 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 9:
809 goes into 4800 5 times with a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 35503.5
Subtract 4045 from 4800 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 10:
The number 809 fits into 7550 9 times, leaving a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 35503.59
The remainder is 269 after subtracting 7281 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 11:
The number 809 fits into 2690 3 times, leaving a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 35503.593
Deduct 2427 from 2690 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 12:
2630 divided by 809 is 3 with a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 35503.5933
If we subtract 2427 from 2630, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

After the division, we end up with 35503.5933 and a remainder of 0.00203.
