We look at the division of 787855 by 71 
The aim is to understand the frequency of 71 in 787855.

Moving on to step 1:
71 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 71

Advancing to step 2:
78 divided by 71 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 71 from 78 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 71

Moving on to step 3:
The number 71 fits into 77 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 71 away from 77, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 71

Advancing to step 4:
If we divide 68 by 71, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 71

Step 5:
71 can be fit into 685 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1109.0
The remainder is 46 after subtracting 639 from 685.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 71

Going ahead to step 6:
71 can be fit into 465 6 times, resulting in a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 11096.0
The remainder is 39 after subtracting 426 from 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
71 can be fit into 390 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 11096.5
If we subtract 355 from 390, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 71, we get 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 11096.54
If we take 284 away from 350, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
660 divided by 71 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 11096.549
The remainder is 21 after subtracting 639 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 71, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 11096.5492
Deduct 142 from 210 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
When dividing 680 by 71, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 11096.54929
If we subtract 639 from 680, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
When dividing 410 by 71, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11096.549295
Subtracting 355 from 410 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
The number 71 fits into 550 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 11096.5492957
Deduct 497 from 550 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 14:
When dividing 530 by 71, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 11096.54929577
The remainder is 33 after subtracting 497 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 11096.54929577 with a remainder of 3.3e-08.
