We're dividing 907973 by 72 
The aim is to understand the frequency of 72 in 907973.

Going ahead to step 1:
When dividing 9 by 72, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 72

Let's proceed to step 2:
72 can be fit into 90 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 90, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 72

Advancing to step 3:
72 can be fit into 187 2 times, resulting in a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 144 from 187 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 72

Going ahead to step 4:
If we divide 439 by 72, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Deduct 432 from 439 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 72

Advancing to step 5:
72 goes into 77 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1261.0
If we subtract 72 from 77, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 72

Going ahead to step 6:
The number 72 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 12610.0
If we take 0 away from 53, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
72 can be fit into 530 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 12610.7
If we subtract 504 from 530, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 72 fits into 260 3 times, leaving a remainder of 44.
The next digit of our result is 3. 
Result so far: 12610.73
Subtracting 216 from 260 leaves us 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.

Advancing to step 9:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 12610.736
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 72, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 12610.7361
If we subtract 72 from 80, we get 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 11:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 12610.73611
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.

Our division results in 12610.73611 with a remaining 8e-06.
