Let's divide 276618 by 28
The aim is to understand the frequency of 28 in 276618.

Going ahead to step 1:
2 divided by 28 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 28

Advancing to step 2:
If we divide 27 by 28, we get 0 and a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 28

Let's proceed to step 3:
When dividing 276 by 28, we get 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 252 from 276, we get 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 28

Advancing to step 4:
28 goes into 246 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 22 after subtracting 224 from 246.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 28

Going ahead to step 5:
28 can be fit into 221 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 987.0
The remainder is 25 after subtracting 196 from 221.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 28

Advancing to step 6:
258 divided by 28 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9879.0
If we subtract 252 from 258, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 28 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9879.2
If we subtract 56 from 60, we 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.

Step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 9879.21
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.

Step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 9879.214
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9879.2142
Subtracting 56 from 80 leaves us 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.

On to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 9879.21428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 9879.214285
Deduct 140 from 160 and we're left 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.

Moving on to step 13:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 9879.2142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 9879.21428571
If we subtract 28 from 40, we get 12.
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 9879.21428571 with a remainder of 1.2e-08.
