We're dividing 42892871 by 817 
The aim is to understand the frequency of 817 in 42892871.

Moving on to step 1:
If we divide 4 by 817, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 817

Going ahead to step 2:
42 divided by 817 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 817

Step 3:
The number 817 fits into 428 0 times, leaving a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Append the next digit (9) from the dividend to 428 and continue with: 4289 / 817

On to step 4:
817 can be fit into 4289 5 times, resulting in a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4085 from 4289 to get 204.
Grab the next digit (2) from the dividend, add it to 204, then carry on: 2042 / 817

Step 5:
When dividing 2042 by 817, we get 2 with a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 1634 from 2042 and we're left with 408.
Include the next digit (8) from the dividend after 408, then repeat: 4088 / 817

Step 6:
If we divide 4088 by 817, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 525.0
The remainder is 3 after subtracting 4085 from 4088.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 817

Advancing to step 7:
When dividing 37 by 817, we get 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 5250.0
Subtract 0 from 37 to get 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 817

Let's proceed to step 8:
371 divided by 817 is 0 with a remainder of 371.
Record the quotient 0 as the next digit in the result. 
Result so far: 52500.0
If we take 0 away from 371, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 9:
When dividing 3710 by 817, we get 4 with a remainder of 442.
Record the quotient 4 as the next digit in the result. 
Result so far: 52500.4
Deduct 3268 from 3710 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 10:
4420 divided by 817 is 5 with a remainder of 335.
The next digit of our result is 5. 
Result so far: 52500.45
The remainder is 335 after subtracting 4085 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
817 can be fit into 3350 4 times, resulting in a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 52500.454
Subtracting 3268 from 3350 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 12:
If we divide 820 by 817, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 52500.4541
Subtracting 817 from 820 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 817 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 52500.4541
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
The number 817 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 52500.4541
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 52500.4541, with a leftover of 3e-05.
