We look at the division of 443022 by 71 
The aim is to understand the frequency of 71 in 443022.

Advancing to step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 71

Advancing to step 2:
If we divide 44 by 71, we get 0 and a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 71

Step 3:
443 divided by 71 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 426 from 443 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 71

On to step 4:
71 goes into 170 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtract 142 from 170 to get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 71

Let's proceed to step 5:
71 goes into 282 3 times with a remainder of 69.
The next digit of our result is 3. 
Result so far: 623.0
Subtracting 213 from 282 leaves us with 69.
Take the next digit (2) from the dividend and append it to 69, then repeat: 692 / 71

Moving on to step 6:
If we divide 692 by 71, we get 9 and a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 6239.0
If we take 639 away from 692, we end up 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.

Step 7:
71 goes into 530 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 6239.7
Subtracting 497 from 530 leaves us with 33.
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:
When dividing 330 by 71, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 6239.74
Deduct 284 from 330 and we're left 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.

Going ahead to step 9:
If we divide 460 by 71, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6239.746
If we subtract 426 from 460, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 71, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 6239.7464
The remainder is 56 after subtracting 284 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
The number 71 fits into 560 7 times, leaving a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 6239.74647
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.

Step 12:
630 divided by 71 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 6239.746478
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.

Going ahead to step 13:
The number 71 fits into 620 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 6239.7464788
If we subtract 568 from 620, we get 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 6239.7464788 with a remainder of 5.2e-07.
