Let's divide 248789 by 28
The aim is to understand the frequency of 28 in 248789.

Advancing to step 1:
When dividing 2 by 28, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 28

Step 2:
24 divided by 28 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 28

Step 3:
The number 28 fits into 248 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 24 after subtracting 224 from 248.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 28

Advancing to step 4:
28 goes into 247 8 times with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 224 from 247 to get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 28

Let's proceed to step 5:
28 can be fit into 238 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 888.0
Subtracting 224 from 238 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 28

Going ahead to step 6:
28 goes into 149 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 8885.0
If we subtract 140 from 149, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 28, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 8885.3
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 28 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8885.32
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 8885.321
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.

Going ahead to step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 8885.3214
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 11:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 8885.32142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8885.321428
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.

Going ahead to step 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 8885.3214285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 8885.32142857
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.

The final outcome is 8885.32142857, with a leftover of 4e-09.
