We're dividing 495857 by 72 
The aim is to understand the frequency of 72 in 495857.

Step 1:
4 divided by 72 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 72

Moving on to step 2:
When dividing 49 by 72, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 72

Advancing to step 3:
72 goes into 495 6 times with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 432 away from 495, we end up with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 72

Going ahead to step 4:
If we divide 638 by 72, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we take 576 away from 638, we end up with 62.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 72

Going ahead to step 5:
The number 72 fits into 625 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
If we subtract 576 from 625, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 72

On to step 6:
497 divided by 72 is 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 6886.0
The remainder is 65 after subtracting 432 from 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
650 divided by 72 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 6886.9
The remainder is 2 after subtracting 648 from 650.
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:
72 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6886.9
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.

Going ahead to step 9:
72 can be fit into 200 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 6886.902
Deduct 144 from 200 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 72, we get 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 6886.9027
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 6886.90277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 6886.90277 and a remainder of 5.6e-05.
