We're dividing 802109 by 71 
The aim is to understand the frequency of 71 in 802109.

Going ahead to step 1:
71 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 71

Advancing to step 2:
71 can be fit into 80 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 71 from 80.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 71

Advancing to step 3:
71 goes into 92 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 21 after subtracting 71 from 92.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 71

Going ahead to step 4:
211 divided by 71 is 2 with a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 112.0
Deduct 142 from 211 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 71

Moving on to step 5:
When dividing 690 by 71, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
If we take 639 away from 690, we end up with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 71

Let's proceed to step 6:
71 goes into 519 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 11297.0
Subtract 497 from 519 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 71, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 11297.3
The remainder is 7 after subtracting 213 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
71 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 11297.3
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
700 divided by 71 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 11297.309
If we take 639 away from 700, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
The number 71 fits into 610 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 11297.3098
Subtract 568 from 610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 71 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 11297.30985
If we subtract 355 from 420, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
71 can be fit into 650 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 11297.309859
If we take 639 away from 650, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
The number 71 fits into 110 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 11297.3098591
Subtract 71 from 110 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
If we divide 390 by 71, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 11297.30985915
If we take 355 away from 390, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 11297.30985915 with a balance of 3.5e-08.
