617544 ÷ 71 
The aim is to understand the frequency of 71 in 617544.

Step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 71

Step 2:
The number 71 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 71

On to step 3:
If we divide 617 by 71, we get 8 and a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 568 from 617 to get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 71

On to step 4:
The number 71 fits into 495 6 times, leaving a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we take 426 away from 495, we end up with 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 71

Going ahead to step 5:
694 divided by 71 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 869.0
If we take 639 away from 694, we end up with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 71

On to step 6:
The number 71 fits into 554 7 times, leaving a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 8697.0
If we subtract 497 from 554, 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.

Step 7:
71 goes into 570 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8697.8
If we subtract 568 from 570, we 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.

Going ahead to step 8:
The number 71 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8697.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
71 goes into 200 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 8697.802
The remainder is 58 after subtracting 142 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
When dividing 580 by 71, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8697.8028
Subtract 568 from 580 to 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.

Moving on to step 11:
When dividing 120 by 71, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 8697.80281
Deduct 71 from 120 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 12:
If we divide 490 by 71, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 8697.802816
If we take 426 away from 490, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
When dividing 640 by 71, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8697.8028169
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.

On to step 14:
When dividing 10 by 71, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8697.8028169
If we take 0 away from 10, we end up 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 result is 8697.8028169 with a remainder of 1e-08.
