We're dividing 413811 by 71 
The aim is to understand the frequency of 71 in 413811.

Advancing to step 1:
The number 71 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 71

Let's proceed to step 2:
71 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 71

Let's proceed to step 3:
When dividing 413 by 71, we get 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 355 from 413 leaves us with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 71

Going ahead to step 4:
If we divide 588 by 71, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Deduct 568 from 588 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 71

Advancing to step 5:
71 can be fit into 201 2 times, resulting in a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 582.0
The remainder is 59 after subtracting 142 from 201.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 71

Going ahead to step 6:
71 goes into 591 8 times with a remainder of 23.
The next digit of our result is 8. 
Result so far: 5828.0
If we take 568 away from 591, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 71 fits into 230 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 5828.3
Subtract 213 from 230 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
When dividing 170 by 71, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5828.32
If we subtract 142 from 170, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 71, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 5828.323
Subtracting 213 from 280 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
When dividing 670 by 71, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 5828.3239
Subtract 639 from 670 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
If we divide 310 by 71, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 5828.32394
If we take 284 away from 310, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
If we divide 260 by 71, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5828.323943
Deduct 213 from 260 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
If we divide 470 by 71, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 5828.3239436
The remainder is 44 after subtracting 426 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
71 goes into 440 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 5828.32394366
Deduct 426 from 440 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 5828.32394366, with a leftover of 1.4e-08.
