We look at the division of 798297 by 72 
The aim is to understand the frequency of 72 in 798297.

On to step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 72

On to step 2:
When dividing 79 by 72, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 79 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 72

Going ahead to step 3:
When dividing 78 by 72, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 72 from 78 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 72

Let's proceed to step 4:
72 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 72

Going ahead to step 5:
When dividing 629 by 72, we get 8 with a remainder of 53.
Put 8 as the next digit of the answer. 
Result so far: 1108.0
Subtracting 576 from 629 leaves us with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 72

Let's proceed to step 6:
72 can be fit into 537 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 11087.0
The remainder is 33 after subtracting 504 from 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
When dividing 330 by 72, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 11087.4
Deduct 288 from 330 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
72 can be fit into 420 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 11087.45
If we subtract 360 from 420, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 11087.458
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 72, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 11087.4583
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 11087.45833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 11087.45833 with a remaining 2.4e-05.
