Let's divide 415993 by 71
The aim is to understand the frequency of 71 in 415993.

Going ahead to step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 71

Moving on to step 2:
When dividing 41 by 71, we get 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 71

Let's proceed to step 3:
71 can be fit into 415 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 60 after subtracting 355 from 415.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 71

Moving on to step 4:
The number 71 fits into 609 8 times, leaving a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 568 from 609 leaves us with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 71

Step 5:
The number 71 fits into 419 5 times, leaving a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 585.0
If we subtract 355 from 419, we get 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 71

Step 6:
643 divided by 71 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 5859.0
Subtracting 639 from 643 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 71 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5859.0
If we take 0 away from 40, we end up 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.

Step 8:
400 divided by 71 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5859.05
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 9:
If we divide 450 by 71, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5859.056
Subtracting 426 from 450 leaves us 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 10:
71 can be fit into 240 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 5859.0563
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.

Moving on to step 11:
270 divided by 71 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 5859.05633
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.

The final result is 5859.05633 with a remainder of 5.7e-05.
