We're dividing 216769 by 28 
The aim is to understand the frequency of 28 in 216769.

Let's proceed to step 1:
If we divide 2 by 28, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 28

Advancing to step 2:
21 divided by 28 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 28

Advancing to step 3:
28 can be fit into 216 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 196 away from 216, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 28

Let's proceed to step 4:
The number 28 fits into 207 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 196 from 207 leaves us with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 28

Moving on to step 5:
28 goes into 116 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 774.0
If we take 112 away from 116, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 28

Step 6:
28 goes into 49 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 7741.0
The remainder is 21 after subtracting 28 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
If we divide 210 by 28, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 7741.7
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 28, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7741.75
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7741.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
28 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7741.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7741.75, and the remainder is 0.0.
