We look at the division of 384250 by 71 
The aim is to understand the frequency of 71 in 384250.

Advancing to step 1:
When dividing 3 by 71, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 71

Moving on to step 2:
38 divided by 71 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 71

Going ahead to step 3:
When dividing 384 by 71, we get 5 with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 355 from 384, we get 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 71

Step 4:
71 can be fit into 292 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 284 from 292 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 71

Let's proceed to step 5:
When dividing 85 by 71, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
The remainder is 14 after subtracting 71 from 85.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 71

Advancing to step 6:
If we divide 140 by 71, we get 1 and a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 5411.0
Subtracting 71 from 140 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 71, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 5411.9
If we subtract 639 from 690, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
When dividing 510 by 71, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5411.97
Subtract 497 from 510 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
71 can be fit into 130 1 times, resulting in a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 5411.971
If we take 71 away from 130, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
When dividing 590 by 71, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 5411.9718
Subtracting 568 from 590 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
If we divide 220 by 71, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 5411.97183
If we subtract 213 from 220, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 71, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5411.97183
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
71 can be fit into 700 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 5411.9718309
If we subtract 639 from 700, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
When dividing 610 by 71, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 5411.97183098
Subtracting 568 from 610 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 5411.97183098 and a remainder of 4.2e-08.
