28827585 divided by 216 
The aim is to understand the frequency of 216 in 28827585.

Moving on to step 1:
2 divided by 216 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 216

Going ahead to step 2:
216 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 216

On to step 3:
216 can be fit into 288 1 times, resulting in a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 216 away from 288, we end up with 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 216

Let's proceed to step 4:
722 divided by 216 is 3 with a remainder of 74.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 648 from 722 and we're left with 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 216

Step 5:
When dividing 747 by 216, we get 3 with a remainder of 99.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 648 from 747 leaves us with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 216

Going ahead to step 6:
216 can be fit into 995 4 times, resulting in a remainder of 131.
Record the quotient 4 as the next digit in the result. 
Result so far: 1334.0
Subtract 864 from 995 to get 131.
Bring next digit (8) of the dividend behind the 131 and repeat the process: 1318 / 216

Let's proceed to step 7:
The number 216 fits into 1318 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 13346.0
Deduct 1296 from 1318 and we're left with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 216

Going ahead to step 8:
If we divide 225 by 216, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 133461.0
If we take 216 away from 225, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
216 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 133461.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
216 goes into 900 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 133461.04
Subtract 864 from 900 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 216, we get 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 133461.041
The remainder is 144 after subtracting 216 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
If we divide 1440 by 216, we get 6 and a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 133461.0416
The remainder is 144 after subtracting 1296 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
When dividing 1440 by 216, we get 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 133461.04166
Subtracting 1296 from 1440 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 133461.04166 with a remainder of 0.000144.
