920987 divided by 72 
The aim is to understand the frequency of 72 in 920987.

Going ahead to step 1:
If we divide 9 by 72, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 72

Step 2:
72 can be fit into 92 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 20 after subtracting 72 from 92.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 72

Going ahead to step 3:
When dividing 200 by 72, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 144 from 200, we get 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 72

Going ahead to step 4:
72 goes into 569 7 times with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 504 from 569 and we're left with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 72

Let's proceed to step 5:
658 divided by 72 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
The remainder is 10 after subtracting 648 from 658.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 72

On to step 6:
When dividing 107 by 72, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 12791.0
Subtract 72 from 107 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
The number 72 fits into 350 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 12791.4
If we subtract 288 from 350, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
72 goes into 620 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 12791.48
Deduct 576 from 620 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.

Moving on to step 9:
When dividing 440 by 72, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 12791.486
Subtract 432 from 440 to 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.

Going ahead to step 10:
72 goes into 80 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 12791.4861
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.

Step 11:
80 divided by 72 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 12791.48611
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.

In conclusion, the division gives 12791.48611 with a balance of 8e-06.
