Let's divide 621297 by 71
The aim is to understand the frequency of 71 in 621297.

Advancing to step 1:
71 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 71

Step 2:
71 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 71

Step 3:
71 goes into 621 8 times with a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 568 away from 621, we end up with 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 71

Going ahead to step 4:
When dividing 532 by 71, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 35 after subtracting 497 from 532.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 71

Moving on to step 5:
If we divide 359 by 71, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 875.0
The remainder is 4 after subtracting 355 from 359.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 71

On to step 6:
When dividing 47 by 71, we get 0 with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 8750.0
If we subtract 0 from 47, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
When dividing 470 by 71, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 8750.6
Subtract 426 from 470 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
71 can be fit into 440 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 8750.66
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 8750.66 with a remainder of 0.014.
