We're dividing 218329 by 28 
The aim is to understand the frequency of 28 in 218329.

Step 1:
If we divide 2 by 28, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 28

Moving on to step 2:
28 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 28

Advancing to step 3:
If we divide 218 by 28, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 196 from 218 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 28

Moving on to step 4:
28 can be fit into 223 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 196 from 223 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 28

Step 5:
The number 28 fits into 272 9 times, leaving a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
If we take 252 away from 272, we end up with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 28

Advancing to step 6:
28 goes into 209 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 7797.0
The remainder is 13 after subtracting 196 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 28, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 7797.4
Subtracting 112 from 130 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 28 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 7797.46
If we take 168 away from 180, we end up 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.

Moving on to step 9:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 7797.464
If we subtract 112 from 120, 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.

Going ahead to step 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 7797.4642
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
28 goes into 240 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7797.46428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 7797.464285
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7797.4642857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
40 divided by 28 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 7797.46428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 7797.46428571 with a remainder of 1.2e-08.
