Let's divide 820040 by 71
The aim is to understand the frequency of 71 in 820040.

On to step 1:
The number 71 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 71

On to step 2:
If we divide 82 by 71, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 71 from 82 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 71

Advancing to step 3:
71 can be fit into 110 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 71 from 110 to get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 71

Advancing to step 4:
When dividing 390 by 71, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we take 355 away from 390, we end up with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 71

Advancing to step 5:
71 goes into 354 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 1154.0
Subtract 284 from 354 to get 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 71

Step 6:
When dividing 700 by 71, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 11549.0
If we subtract 639 from 700, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
71 can be fit into 610 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 11549.8
The remainder is 42 after subtracting 568 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
If we divide 420 by 71, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 11549.85
Subtract 355 from 420 to 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.

Moving on to step 9:
If we divide 650 by 71, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 11549.859
Deduct 639 from 650 and we're left 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.

Going ahead to step 10:
When dividing 110 by 71, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 11549.8591
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 11:
The number 71 fits into 390 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 11549.85915
Subtracting 355 from 390 leaves us 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.

On to step 12:
350 divided by 71 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 11549.859154
Subtracting 284 from 350 leaves us 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.

Moving on to step 13:
If we divide 660 by 71, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 11549.8591549
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 14:
210 divided by 71 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 11549.85915492
If we subtract 142 from 210, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 11549.85915492 with a balance of 6.8e-08.
