72863 ÷ 71 
The aim is to understand the frequency of 71 in 72863.

On to step 1:
If we divide 7 by 71, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 71

Step 2:
When dividing 72 by 71, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 71 from 72.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 71

On to step 3:
71 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 71

Step 4:
When dividing 186 by 71, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we subtract 142 from 186, we get 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 71

Going ahead to step 5:
71 goes into 443 6 times with a remainder of 17.
The next digit of our result is 6. 
Result so far: 1026.0
If we subtract 426 from 443, we 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.

Advancing to step 6:
71 goes into 170 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1026.2
If we take 142 away from 170, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
280 divided by 71 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1026.23
The remainder is 67 after subtracting 213 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
The number 71 fits into 670 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1026.239
Deduct 639 from 670 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
71 can be fit into 310 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 1026.2394
Subtracting 284 from 310 leaves us 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.

Moving on to step 10:
When dividing 260 by 71, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1026.23943
Subtracting 213 from 260 leaves us 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.

Going ahead to step 11:
470 divided by 71 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1026.239436
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.

Let's proceed to step 12:
71 goes into 440 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1026.2394366
If we take 426 away from 440, we end up 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.

After the division, we end up with 1026.2394366 and a remainder of 1.4e-07.
