We look at the division of 515448 by 71 
The aim is to understand the frequency of 71 in 515448.

Going ahead to step 1:
71 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 71

Step 2:
If we divide 51 by 71, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 71

Going ahead to step 3:
When dividing 515 by 71, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 497 from 515, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 71

Going ahead to step 4:
184 divided by 71 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtract 142 from 184 to get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 71

Moving on to step 5:
If we divide 424 by 71, we get 5 and a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 725.0
Subtract 355 from 424 to get 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 71

Going ahead to step 6:
If we divide 698 by 71, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 7259.0
If we subtract 639 from 698, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
When dividing 590 by 71, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7259.8
The remainder is 22 after subtracting 568 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
220 divided by 71 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7259.83
The remainder is 7 after subtracting 213 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
70 divided by 71 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7259.83
If we take 0 away from 70, we end up 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.

Advancing to step 10:
700 divided by 71 is 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 7259.8309
The remainder is 61 after subtracting 639 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
When dividing 610 by 71, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 7259.83098
If we take 568 away from 610, we end up 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.

Advancing to step 12:
If we divide 420 by 71, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7259.830985
Subtract 355 from 420 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
The number 71 fits into 650 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 7259.8309859
Subtracting 639 from 650 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
When dividing 110 by 71, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 7259.83098591
If we subtract 71 from 110, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 7259.83098591 with a remaining 3.9e-08.
