28713058 divided by 817 
The aim is to understand the frequency of 817 in 28713058.

Going ahead to step 1:
If we divide 2 by 817, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 817

Moving on to step 2:
When dividing 28 by 817, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 817

Step 3:
817 goes into 287 0 times with a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 287 leaves us with 287.
Bring next digit (1) of the dividend behind the 287 and repeat the process: 2871 / 817

Let's proceed to step 4:
2871 divided by 817 is 3 with a remainder of 420.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2451 from 2871 leaves us with 420.
Fetch the next digit (3) from the dividend, attach it to 420 and continue: 4203 / 817

Advancing to step 5:
817 goes into 4203 5 times with a remainder of 118.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 4085 from 4203 and we're left with 118.
Grab the next digit (0) from the dividend, add it to 118, then carry on: 1180 / 817

Moving on to step 6:
The number 817 fits into 1180 1 times, leaving a remainder of 363.
Use 1 as the next digit of our solution. 
Result so far: 351.0
Subtract 817 from 1180 to get 363.
Bring next digit (5) of the dividend behind the 363 and repeat the process: 3635 / 817

Moving on to step 7:
3635 divided by 817 is 4 with a remainder of 367.
The number 4 becomes the next digit in our result. 
Result so far: 3514.0
If we subtract 3268 from 3635, we get 367.
Grab the next digit (8) from the dividend, add it to 367, then carry on: 3678 / 817

Going ahead to step 8:
817 goes into 3678 4 times with a remainder of 410.
Use 4 as the next digit of our solution. 
Result so far: 35144.0
Subtract 3268 from 3678 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 9:
817 goes into 4100 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 35144.5
Subtracting 4085 from 4100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
817 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 35144.5
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
1500 divided by 817 is 1 with a remainder of 683.
Write down 1 as next digit of the result. 
Result so far: 35144.501
The remainder is 683 after subtracting 817 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Let's proceed to step 12:
817 can be fit into 6830 8 times, resulting in a remainder of 294.
The next digit of our result is 8. 
Result so far: 35144.5018
Deduct 6536 from 6830 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 13:
817 can be fit into 2940 3 times, resulting in a remainder of 489.
The next digit of our result is 3. 
Result so far: 35144.50183
If we take 2451 away from 2940, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 14:
When dividing 4890 by 817, we get 5 with a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 35144.501835
The remainder is 805 after subtracting 4085 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 15:
817 goes into 8050 9 times with a remainder of 697.
Write down 9 as next digit of the result. 
Result so far: 35144.5018359
If we take 7353 away from 8050, we end up with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Advancing to step 16:
When dividing 6970 by 817, we get 8 with a remainder of 434.
The next digit of our result is 8. 
Result so far: 35144.50183598
If we take 6536 away from 6970, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Our division results in 35144.50183598 with a remaining 4.34e-07.
