791252 divided by 72 
The aim is to understand the frequency of 72 in 791252.

On to step 1:
72 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 72

On to step 2:
72 goes into 79 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 72 from 79 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 72

Let's proceed to step 3:
The number 72 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 72

Going ahead to step 4:
72 goes into 712 9 times with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtract 648 from 712 to get 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 72

Advancing to step 5:
If we divide 645 by 72, we get 8 and a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 1098.0
Deduct 576 from 645 and we're left with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 72

Let's proceed to step 6:
72 goes into 692 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 10989.0
Deduct 648 from 692 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 72, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10989.6
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 10989.61
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 10989.611
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10989.611 and a remainder of 0.0008.
