We look at the division of 400071 by 71 
The aim is to understand the frequency of 71 in 400071.

Advancing to step 1:
71 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 71

Let's proceed to step 2:
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: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 71

Let's proceed to step 3:
If we divide 400 by 71, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 355 from 400 and we're left with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 71

Let's proceed to step 4:
When dividing 450 by 71, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtract 426 from 450 to get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 71

On to step 5:
When dividing 247 by 71, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 563.0
The remainder is 34 after subtracting 213 from 247.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 71

Let's proceed to step 6:
If we divide 341 by 71, we get 4 and a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 5634.0
If we subtract 284 from 341, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
570 divided by 71 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5634.8
Subtracting 568 from 570 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
71 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5634.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 71, we get 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 5634.802
Subtract 142 from 200 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
71 goes into 580 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5634.8028
If we take 568 away from 580, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
71 goes into 120 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 5634.80281
Subtract 71 from 120 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
490 divided by 71 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 5634.802816
The remainder is 64 after subtracting 426 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
640 divided by 71 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5634.8028169
If we take 639 away from 640, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
71 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5634.8028169
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 5634.8028169 with a remainder of 1e-08.
