405680 divided by 71 
The aim is to understand the frequency of 71 in 405680.

On 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

Step 2:
71 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 71

Advancing to step 3:
When dividing 405 by 71, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 355 away from 405, we end up with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 71

Let's proceed to step 4:
When dividing 506 by 71, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 9 after subtracting 497 from 506.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 71

Going ahead to step 5:
71 goes into 98 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 571.0
Deduct 71 from 98 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 71

Going ahead to step 6:
71 can be fit into 270 3 times, resulting in a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 5713.0
Subtracting 213 from 270 leaves us 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.

Advancing to step 7:
The number 71 fits into 570 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 5713.8
Subtract 568 from 570 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

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: 5713.8
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.

Step 9:
200 divided by 71 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 5713.802
If we take 142 away from 200, we end up with 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:
If we divide 580 by 71, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 5713.8028
If we subtract 568 from 580, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
71 goes into 120 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 5713.80281
The remainder is 49 after subtracting 71 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
When dividing 490 by 71, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5713.802816
Subtract 426 from 490 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
640 divided by 71 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5713.8028169
If we subtract 639 from 640, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
If we divide 10 by 71, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 5713.8028169
Subtracting 0 from 10 leaves us with 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 outcome is 5713.8028169, with a leftover of 1e-08.
