28963 ÷ 30 
The aim is to understand the frequency of 30 in 28963.

Let's proceed to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 30

Going ahead to step 2:
The number 30 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 30

Advancing to step 3:
If we divide 289 by 30, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 270 from 289 to get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 30

Let's proceed to step 4:
When dividing 196 by 30, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 16 after subtracting 180 from 196.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 30

Going ahead to step 5:
163 divided by 30 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 965.0
Subtracting 150 from 163 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 6:
30 goes into 130 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 965.4
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 965.43
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 965.433
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 965.433, with a leftover of 0.001.
