We're dividing 98640119 by 817 
The aim is to understand the frequency of 817 in 98640119.

Going ahead to step 1:
9 divided by 817 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 817

Going ahead to step 2:
817 goes into 98 0 times with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 817

On to step 3:
817 can be fit into 986 1 times, resulting in a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 817 away from 986, we end up with 169.
Grab the next digit (4) from the dividend, add it to 169, then carry on: 1694 / 817

Advancing to step 4:
When dividing 1694 by 817, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 60 after subtracting 1634 from 1694.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 817

Advancing to step 5:
600 divided by 817 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 600 to get 600.
Take the next digit (1) from the dividend and append it to 600, then repeat: 6001 / 817

Moving on to step 6:
If we divide 6001 by 817, we get 7 and a remainder of 282.
Write down 7 as next digit of the result. 
Result so far: 1207.0
Subtracting 5719 from 6001 leaves us with 282.
Take the next digit (1) from the dividend and append it to 282, then repeat: 2821 / 817

Step 7:
817 can be fit into 2821 3 times, resulting in a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 12073.0
Deduct 2451 from 2821 and we're left with 370.
Fetch the next digit (9) from the dividend, attach it to 370 and continue: 3709 / 817

Let's proceed to step 8:
The number 817 fits into 3709 4 times, leaving a remainder of 441.
The number 4 becomes the next digit in our result. 
Result so far: 120734.0
Deduct 3268 from 3709 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 9:
The number 817 fits into 4410 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 120734.5
Deduct 4085 from 4410 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
817 goes into 3250 3 times with a remainder of 799.
Record the quotient 3 as the next digit in the result. 
Result so far: 120734.53
Deduct 2451 from 3250 and we're left with 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Moving on to step 11:
7990 divided by 817 is 9 with a remainder of 637.
The number 9 becomes the next digit in our result. 
Result so far: 120734.539
If we subtract 7353 from 7990, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 12:
817 goes into 6370 7 times with a remainder of 651.
The next digit of our result is 7. 
Result so far: 120734.5397
Subtracting 5719 from 6370 leaves us with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Moving on to step 13:
When dividing 6510 by 817, we get 7 with a remainder of 791.
The number 7 becomes the next digit in our result. 
Result so far: 120734.53977
If we take 5719 away from 6510, we end up with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Our division results in 120734.53977 with a remaining 0.000791.
