We're dividing 15180346 by 817 
The aim is to understand the frequency of 817 in 15180346.

Going ahead to step 1:
If we divide 1 by 817, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 817

Step 2:
If we divide 15 by 817, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 817

Step 3:
151 divided by 817 is 0 with a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Include the next digit (8) from the dividend after 151, then repeat: 1518 / 817

On to step 4:
The number 817 fits into 1518 1 times, leaving a remainder of 701.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 817 from 1518 and we're left with 701.
Include the next digit (0) from the dividend after 701, then repeat: 7010 / 817

Step 5:
The number 817 fits into 7010 8 times, leaving a remainder of 474.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 6536 from 7010 and we're left with 474.
Fetch the next digit (3) from the dividend, attach it to 474 and continue: 4743 / 817

Step 6:
817 goes into 4743 5 times with a remainder of 658.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we subtract 4085 from 4743, we get 658.
Fetch the next digit (4) from the dividend, attach it to 658 and continue: 6584 / 817

Going ahead to step 7:
When dividing 6584 by 817, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1858.0
The remainder is 48 after subtracting 6536 from 6584.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 817

Moving on to step 8:
486 divided by 817 is 0 with a remainder of 486.
The next digit of our result is 0. 
Result so far: 18580.0
If we subtract 0 from 486, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 9:
The number 817 fits into 4860 5 times, leaving a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 18580.5
Subtracting 4085 from 4860 leaves us with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Moving on to step 10:
7750 divided by 817 is 9 with a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 18580.59
Subtracting 7353 from 7750 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 11:
817 can be fit into 3970 4 times, resulting in a remainder of 702.
The next digit of our result is 4. 
Result so far: 18580.594
Subtract 3268 from 3970 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

On to step 12:
7020 divided by 817 is 8 with a remainder of 484.
The next digit of our result is 8. 
Result so far: 18580.5948
Subtracting 6536 from 7020 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 13:
4840 divided by 817 is 5 with a remainder of 755.
Write down 5 as next digit of the result. 
Result so far: 18580.59485
If we take 4085 away from 4840, we end up with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Going ahead to step 14:
When dividing 7550 by 817, we get 9 with a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 18580.594859
Deduct 7353 from 7550 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 15:
When dividing 1970 by 817, we get 2 with a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 18580.5948592
If we take 1634 away from 1970, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 16:
817 can be fit into 3360 4 times, resulting in a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 18580.59485924
If we subtract 3268 from 3360, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

After the division, we end up with 18580.59485924 and a remainder of 9.2e-08.
