28530859 ÷ 819 
We want to figure out the number of times 28530859 can be divided by 819.

On to step 1:
819 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 819

Moving on to step 2:
28 divided by 819 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 819

Moving on to step 3:
819 goes into 285 0 times with a remainder of 285.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 285, we end up with 285.
Fetch the next digit (3) from the dividend, attach it to 285 and continue: 2853 / 819

Moving on to step 4:
819 can be fit into 2853 3 times, resulting in a remainder of 396.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2457 from 2853 leaves us with 396.
Bring next digit (0) of the dividend behind the 396 and repeat the process: 3960 / 819

Let's proceed to step 5:
3960 divided by 819 is 4 with a remainder of 684.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 3276 away from 3960, we end up with 684.
Append the next digit (8) from the dividend to 684 and continue with: 6848 / 819

Advancing to step 6:
The number 819 fits into 6848 8 times, leaving a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
Deduct 6552 from 6848 and we're left with 296.
Append the next digit (5) from the dividend to 296 and continue with: 2965 / 819

Let's proceed to step 7:
2965 divided by 819 is 3 with a remainder of 508.
Write down 3 as next digit of the result. 
Result so far: 3483.0
Subtract 2457 from 2965 to get 508.
Include the next digit (9) from the dividend after 508, then repeat: 5089 / 819

Advancing to step 8:
819 goes into 5089 6 times with a remainder of 175.
The number 6 becomes the next digit in our result. 
Result so far: 34836.0
Deduct 4914 from 5089 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
819 can be fit into 1750 2 times, resulting in a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 34836.2
If we take 1638 away from 1750, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 10:
The number 819 fits into 1120 1 times, leaving a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 34836.21
If we take 819 away from 1120, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 11:
If we divide 3010 by 819, we get 3 and a remainder of 553.
The next digit of our result is 3. 
Result so far: 34836.213
Subtracting 2457 from 3010 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 12:
If we divide 5530 by 819, we get 6 and a remainder of 616.
Put 6 as the next digit of the answer. 
Result so far: 34836.2136
If we subtract 4914 from 5530, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
819 can be fit into 6160 7 times, resulting in a remainder of 427.
Record the quotient 7 as the next digit in the result. 
Result so far: 34836.21367
Subtract 5733 from 6160 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 14:
819 can be fit into 4270 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 34836.213675
If we take 4095 away from 4270, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 15:
If we divide 1750 by 819, we get 2 and a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 34836.2136752
If we subtract 1638 from 1750, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
When dividing 1120 by 819, we get 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 34836.21367521
If we subtract 819 from 1120, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final result is 34836.21367521 with a remainder of 3.01e-07.
