400447 ÷ 71 
The aim is to understand the frequency of 71 in 400447.

Advancing 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
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

Going ahead to step 2:
71 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 71

Advancing to step 3:
71 goes into 400 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 355 from 400 and we're left with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 71

Let's proceed to step 4:
71 goes into 454 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 426 from 454, we get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 71

On to step 5:
If we divide 284 by 71, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 564.0
The remainder is 0 after subtracting 284 from 284.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 71

On to step 6:
7 divided by 71 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 5640.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 71, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5640.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
71 goes into 700 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 5640.09
If we take 639 away from 700, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
If we divide 610 by 71, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 5640.098
Deduct 568 from 610 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
The number 71 fits into 420 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 5640.0985
Subtract 355 from 420 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
If we divide 650 by 71, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 5640.09859
Subtracting 639 from 650 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
71 can be fit into 110 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 5640.098591
The remainder is 39 after subtracting 71 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
390 divided by 71 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5640.0985915
Subtract 355 from 390 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
71 goes into 350 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 5640.09859154
The remainder is 66 after subtracting 284 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 5640.09859154 with a remaining 6.6e-08.
