We look at the division of 405595 by 71 
The aim is to understand the frequency of 71 in 405595.

Going ahead to step 1:
The number 71 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 71

Step 2:
40 divided by 71 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 71

On to step 3:
The number 71 fits into 405 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 355 from 405 leaves us with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 71

Going ahead to step 4:
If we divide 505 by 71, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we take 497 away from 505, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 71

Step 5:
When dividing 89 by 71, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 571.0
Subtracting 71 from 89 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 71

Let's proceed to step 6:
The number 71 fits into 185 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 5712.0
Subtracting 142 from 185 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
The number 71 fits into 430 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 5712.6
The remainder is 4 after subtracting 426 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
71 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5712.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5712.605
The remainder is 45 after subtracting 355 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
71 goes into 450 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5712.6056
Deduct 426 from 450 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 71, we get 3 and a remainder of 27.
The next digit of our result is 3. 
Result so far: 5712.60563
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
The number 71 fits into 270 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 5712.605633
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 5712.605633 with a balance of 5.7e-06.
