We're dividing 628051 by 71 
The aim is to understand the frequency of 71 in 628051.

Going ahead to step 1:
71 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 71

On to step 2:
62 divided by 71 is 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 71

Going ahead to step 3:
The number 71 fits into 628 8 times, leaving a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 568 from 628 and we're left with 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 71

Step 4:
600 divided by 71 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 568 from 600 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 71

Moving on to step 5:
71 goes into 325 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 884.0
Subtract 284 from 325 to get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 71

Step 6:
The number 71 fits into 411 5 times, leaving a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 8845.0
If we subtract 355 from 411, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
71 can be fit into 560 7 times, resulting in a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 8845.7
If we subtract 497 from 560, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
71 goes into 630 8 times with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 8845.78
Deduct 568 from 630 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
The number 71 fits into 620 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 8845.788
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 8845.788 with a remainder of 0.0052.
