We're dividing 907197 by 72 
The aim is to understand the frequency of 72 in 907197.

Let's proceed to step 1:
9 divided by 72 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 72

Moving on to step 2:
The number 72 fits into 90 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 72 away from 90, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 72

Going ahead to step 3:
If we divide 187 by 72, we get 2 and a remainder of 43.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 144 from 187 and we're left with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 72

Let's proceed to step 4:
The number 72 fits into 431 5 times, leaving a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 360 from 431 leaves us with 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 72

Going ahead to step 5:
72 can be fit into 719 9 times, resulting in a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 1259.0
The remainder is 71 after subtracting 648 from 719.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 72

Step 6:
The number 72 fits into 717 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 12599.0
If we take 648 away from 717, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
72 can be fit into 690 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 12599.9
If we take 648 away from 690, we end up 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.

Moving on to step 8:
420 divided by 72 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 12599.95
Subtract 360 from 420 to 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.

Step 9:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12599.958
The remainder is 24 after subtracting 576 from 600.
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:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 12599.9583
If we subtract 216 from 240, we 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.

Moving on to step 11:
When dividing 240 by 72, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 12599.95833
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.

The final result is 12599.95833 with a remainder of 2.4e-05.
