We're dividing 806831 by 71 
The aim is to understand the frequency of 71 in 806831.

Let's proceed to step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 71

Let's proceed to step 2:
80 divided by 71 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 71 from 80.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 71

Let's proceed to step 3:
When dividing 96 by 71, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 71 from 96 to get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 71

Moving on to step 4:
71 goes into 258 3 times with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 113.0
The remainder is 45 after subtracting 213 from 258.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 71

Advancing to step 5:
When dividing 453 by 71, we get 6 with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 1136.0
Subtract 426 from 453 to get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 71

On to step 6:
The number 71 fits into 271 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 11363.0
If we subtract 213 from 271, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
71 goes into 580 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11363.8
Deduct 568 from 580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 71 fits into 120 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 11363.81
Subtracting 71 from 120 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
The number 71 fits into 490 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 11363.816
If we subtract 426 from 490, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 71 fits into 640 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11363.8169
If we take 639 away from 640, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
71 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11363.8169
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
71 goes into 100 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 11363.816901
Deduct 71 from 100 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
The number 71 fits into 290 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 11363.8169014
Deduct 284 from 290 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
71 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 11363.8169014
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 11363.8169014, with a leftover of 6e-08.
