We look at the division of 72287911 by 288 
The aim is to understand the frequency of 288 in 72287911.

Let's proceed to step 1:
7 divided by 288 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 288

Step 2:
If we divide 72 by 288, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 288

Moving on to step 3:
If we divide 722 by 288, we get 2 and a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 576 from 722 to get 146.
Bring next digit (8) of the dividend behind the 146 and repeat the process: 1468 / 288

Let's proceed to step 4:
1468 divided by 288 is 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 1440 from 1468 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 288

On to step 5:
288 can be fit into 287 0 times, resulting in a remainder of 287.
The next digit of our result is 0. 
Result so far: 250.0
The remainder is 287 after subtracting 0 from 287.
Fetch the next digit (9) from the dividend, attach it to 287 and continue: 2879 / 288

Moving on to step 6:
288 can be fit into 2879 9 times, resulting in a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 2509.0
If we take 2592 away from 2879, we end up with 287.
Bring next digit (1) of the dividend behind the 287 and repeat the process: 2871 / 288

Going ahead to step 7:
288 can be fit into 2871 9 times, resulting in a remainder of 279.
The next digit of our result is 9. 
Result so far: 25099.0
Deduct 2592 from 2871 and we're left with 279.
Take the next digit (1) from the dividend and append it to 279, then repeat: 2791 / 288

Moving on to step 8:
288 goes into 2791 9 times with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 250999.0
If we subtract 2592 from 2791, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
When dividing 1990 by 288, we get 6 with a remainder of 262.
Put 6 as the next digit of the answer. 
Result so far: 250999.6
Deduct 1728 from 1990 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 10:
If we divide 2620 by 288, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 250999.69
Subtracting 2592 from 2620 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
280 divided by 288 is 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 250999.69
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
288 can be fit into 2800 9 times, resulting in a remainder of 208.
Write down 9 as next digit of the result. 
Result so far: 250999.6909
If we subtract 2592 from 2800, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
If we divide 2080 by 288, we get 7 and a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 250999.69097
Subtract 2016 from 2080 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
288 can be fit into 640 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 250999.690972
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
288 goes into 640 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 250999.6909722
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 250999.6909722 with a balance of 6.4e-07.
