789681 divided by 72 
The aim is to understand the frequency of 72 in 789681.

Going ahead to step 1:
72 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 72

Going ahead to step 2:
The number 72 fits into 78 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 78, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 72

Advancing to step 3:
The number 72 fits into 69 0 times, leaving a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 69, we get 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 72

Moving on to step 4:
72 can be fit into 696 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 648 from 696 and we're left with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 72

Step 5:
488 divided by 72 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 1096.0
Subtract 432 from 488 to get 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 72

Advancing to step 6:
When dividing 561 by 72, we get 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 10967.0
Deduct 504 from 561 and we're left 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.

On to step 7:
72 can be fit into 570 7 times, resulting in a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 10967.7
If we take 504 away from 570, we end up 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.

On to step 8:
The number 72 fits into 660 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 10967.79
Subtracting 648 from 660 leaves us 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.

Advancing to step 9:
72 goes into 120 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 10967.791
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10967.7916
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
When dividing 480 by 72, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 10967.79166
Subtract 432 from 480 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.

The final result is 10967.79166 with a remainder of 4.8e-05.
