Let's divide 28133841 by 817
The aim is to understand the frequency of 817 in 28133841.

Going ahead to step 1:
817 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 817

Advancing to step 2:
28 divided by 817 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 817

Advancing to step 3:
817 can be fit into 281 0 times, resulting in a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 281 to get 281.
Grab the next digit (3) from the dividend, add it to 281, then carry on: 2813 / 817

Going ahead to step 4:
The number 817 fits into 2813 3 times, leaving a remainder of 362.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2451 away from 2813, we end up with 362.
Fetch the next digit (3) from the dividend, attach it to 362 and continue: 3623 / 817

Step 5:
If we divide 3623 by 817, we get 4 and a remainder of 355.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 3268 from 3623, we get 355.
Include the next digit (8) from the dividend after 355, then repeat: 3558 / 817

Step 6:
3558 divided by 817 is 4 with a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
Subtracting 3268 from 3558 leaves us with 290.
Append the next digit (4) from the dividend to 290 and continue with: 2904 / 817

Moving on to step 7:
817 goes into 2904 3 times with a remainder of 453.
Use 3 as the next digit of our solution. 
Result so far: 3443.0
The remainder is 453 after subtracting 2451 from 2904.
Fetch the next digit (1) from the dividend, attach it to 453 and continue: 4531 / 817

Advancing to step 8:
If we divide 4531 by 817, we get 5 and a remainder of 446.
The number 5 becomes the next digit in our result. 
Result so far: 34435.0
If we take 4085 away from 4531, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
817 goes into 4460 5 times with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 34435.5
Deduct 4085 from 4460 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 10:
The number 817 fits into 3750 4 times, leaving a remainder of 482.
The number 4 becomes the next digit in our result. 
Result so far: 34435.54
If we take 3268 away from 3750, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 11:
4820 divided by 817 is 5 with a remainder of 735.
The number 5 becomes the next digit in our result. 
Result so far: 34435.545
The remainder is 735 after subtracting 4085 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 12:
If we divide 7350 by 817, we get 8 and a remainder of 814.
Write down 8 as next digit of the result. 
Result so far: 34435.5458
If we subtract 6536 from 7350, we get 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Advancing to step 13:
8140 divided by 817 is 9 with a remainder of 787.
Use 9 as the next digit of our solution. 
Result so far: 34435.54589
The remainder is 787 after subtracting 7353 from 8140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Let's proceed to step 14:
If we divide 7870 by 817, we get 9 and a remainder of 517.
The number 9 becomes the next digit in our result. 
Result so far: 34435.545899
If we subtract 7353 from 7870, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

The final outcome is 34435.545899, with a leftover of 5.17e-05.
