28504915 divided by 815 
We want to figure out the number of times 28504915 can be divided by 815.

Advancing to step 1:
If we divide 2 by 815, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 815

On to step 2:
The number 815 fits into 28 0 times, leaving a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 815

Advancing to step 3:
815 goes into 285 0 times with a remainder of 285.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 285 after subtracting 0 from 285.
Include the next digit (0) from the dividend after 285, then repeat: 2850 / 815

Step 4:
When dividing 2850 by 815, we get 3 with a remainder of 405.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2445 from 2850 and we're left with 405.
Fetch the next digit (4) from the dividend, attach it to 405 and continue: 4054 / 815

Advancing to step 5:
815 can be fit into 4054 4 times, resulting in a remainder of 794.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 3260 from 4054 to get 794.
Take the next digit (9) from the dividend and append it to 794, then repeat: 7949 / 815

Going ahead to step 6:
When dividing 7949 by 815, we get 9 with a remainder of 614.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
If we subtract 7335 from 7949, we get 614.
Grab the next digit (1) from the dividend, add it to 614, then carry on: 6141 / 815

Let's proceed to step 7:
The number 815 fits into 6141 7 times, leaving a remainder of 436.
Use 7 as the next digit of our solution. 
Result so far: 3497.0
Subtract 5705 from 6141 to get 436.
Fetch the next digit (5) from the dividend, attach it to 436 and continue: 4365 / 815

Moving on to step 8:
4365 divided by 815 is 5 with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 34975.0
If we subtract 4075 from 4365, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 9:
The number 815 fits into 2900 3 times, leaving a remainder of 455.
Record the quotient 3 as the next digit in the result. 
Result so far: 34975.3
Subtract 2445 from 2900 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 10:
When dividing 4550 by 815, we get 5 with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 34975.35
Subtracting 4075 from 4550 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 11:
When dividing 4750 by 815, we get 5 with a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 34975.355
If we subtract 4075 from 4750, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

The final result is 34975.355 with a remainder of 0.0675.
