We look at the division of 80200789 by 814 
The aim is to understand the frequency of 814 in 80200789.

Advancing to step 1:
814 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 814

Moving on to step 2:
The number 814 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 814

Moving on to step 3:
The number 814 fits into 802 0 times, leaving a remainder of 802.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 802, we get 802.
Fetch the next digit (0) from the dividend, attach it to 802 and continue: 8020 / 814

On to step 4:
If we divide 8020 by 814, we get 9 and a remainder of 694.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7326 from 8020 to get 694.
Take the next digit (0) from the dividend and append it to 694, then repeat: 6940 / 814

Advancing to step 5:
814 can be fit into 6940 8 times, resulting in a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 6512 from 6940, we get 428.
Grab the next digit (7) from the dividend, add it to 428, then carry on: 4287 / 814

On to step 6:
The number 814 fits into 4287 5 times, leaving a remainder of 217.
Record the quotient 5 as the next digit in the result. 
Result so far: 985.0
Subtracting 4070 from 4287 leaves us with 217.
Bring next digit (8) of the dividend behind the 217 and repeat the process: 2178 / 814

Advancing to step 7:
When dividing 2178 by 814, we get 2 with a remainder of 550.
The number 2 becomes the next digit in our result. 
Result so far: 9852.0
The remainder is 550 after subtracting 1628 from 2178.
Fetch the next digit (9) from the dividend, attach it to 550 and continue: 5509 / 814

On to step 8:
814 goes into 5509 6 times with a remainder of 625.
Use 6 as the next digit of our solution. 
Result so far: 98526.0
If we take 4884 away from 5509, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 9:
814 goes into 6250 7 times with a remainder of 552.
Write down 7 as next digit of the result. 
Result so far: 98526.7
If we take 5698 away from 6250, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 10:
When dividing 5520 by 814, we get 6 with a remainder of 636.
Write down 6 as next digit of the result. 
Result so far: 98526.76
Subtracting 4884 from 5520 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 11:
6360 divided by 814 is 7 with a remainder of 662.
The number 7 becomes the next digit in our result. 
Result so far: 98526.767
If we subtract 5698 from 6360, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 12:
6620 divided by 814 is 8 with a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 98526.7678
Subtract 6512 from 6620 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 13:
1080 divided by 814 is 1 with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 98526.76781
Subtract 814 from 1080 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 14:
2660 divided by 814 is 3 with a remainder of 218.
Use 3 as the next digit of our solution. 
Result so far: 98526.767813
If we subtract 2442 from 2660, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 15:
If we divide 2180 by 814, we get 2 and a remainder of 552.
Put 2 as the next digit of the answer. 
Result so far: 98526.7678132
Deduct 1628 from 2180 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 16:
The number 814 fits into 5520 6 times, leaving a remainder of 636.
The next digit of our result is 6. 
Result so far: 98526.76781326
Subtract 4884 from 5520 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

After the division, we end up with 98526.76781326 and a remainder of 6.36e-07.
