728697 ÷ 72 
The aim is to understand the frequency of 72 in 728697.

Going ahead to step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 72

Let's proceed to step 2:
72 can be fit into 72 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 72 from 72 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 72

Moving on to step 3:
72 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 72

Step 4:
72 goes into 86 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 101.0
If we subtract 72 from 86, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 72

Advancing to step 5:
72 can be fit into 149 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 1012.0
Deduct 144 from 149 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 72

Let's proceed to step 6:
72 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 10120.0
Subtracting 0 from 57 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.

Let's proceed to step 7:
72 can be fit into 570 7 times, resulting in a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 10120.7
Subtracting 504 from 570 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
660 divided by 72 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 10120.79
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 10120.791
Subtract 72 from 120 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
72 goes into 480 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 10120.7916
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 10120.79166
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 10120.79166, and the remainder is 4.8e-05.
