We look at the division of 624711 by 71 
The aim is to understand the frequency of 71 in 624711.

Advancing to step 1:
71 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 71

Step 2:
When dividing 62 by 71, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 71

On to step 3:
When dividing 624 by 71, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 568 away from 624, we end up with 56.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 71

Let's proceed to step 4:
71 goes into 567 7 times with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 497 from 567 and we're left with 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 71

Going ahead to step 5:
701 divided by 71 is 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 879.0
Deduct 639 from 701 and we're left with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 71

Going ahead to step 6:
71 can be fit into 621 8 times, resulting in a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 8798.0
Deduct 568 from 621 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
71 can be fit into 530 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 8798.7
The remainder is 33 after subtracting 497 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
The number 71 fits into 330 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 8798.74
If we take 284 away from 330, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
If we divide 460 by 71, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 8798.746
Deduct 426 from 460 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 71, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 8798.7464
Subtracting 284 from 340 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
560 divided by 71 is 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 8798.74647
Deduct 497 from 560 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
The number 71 fits into 630 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 8798.746478
The remainder is 62 after subtracting 568 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
The number 71 fits into 620 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8798.7464788
Subtracting 568 from 620 leaves us 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 8798.7464788 with a remainder of 5.2e-07.
