We're dividing 280821 by 71 
The aim is to understand the frequency of 71 in 280821.

Advancing to step 1:
71 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 71

Let's proceed to step 2:
71 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 71

Advancing to step 3:
71 goes into 280 3 times with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 67 after subtracting 213 from 280.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 71

Going ahead to step 4:
The number 71 fits into 678 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 639 from 678 to get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 71

Advancing to step 5:
71 can be fit into 392 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 395.0
The remainder is 37 after subtracting 355 from 392.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 71

Going ahead to step 6:
71 goes into 371 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 3955.0
Subtracting 355 from 371 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 71, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 3955.2
Subtracting 142 from 160 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 71, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 3955.22
Subtract 142 from 180 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 3955.22 with a balance of 0.038.
