626623 divided by 28 
The aim is to understand the frequency of 28 in 626623.

Going ahead to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 28

Going ahead to step 2:
If we divide 62 by 28, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 56 from 62.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 28

Moving on to step 3:
66 divided by 28 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 10 after subtracting 56 from 66.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 28

Going ahead to step 4:
If we divide 106 by 28, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 223.0
Subtracting 84 from 106 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 28

Step 5:
28 can be fit into 222 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 2237.0
If we take 196 away from 222, we end up with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 28

Moving on to step 6:
When dividing 263 by 28, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 22379.0
Subtract 252 from 263 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 28 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 22379.3
If we subtract 84 from 110, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 28, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 22379.39
If we take 252 away from 260, we end up with 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 9:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 22379.392
If we take 56 away from 80, we end up 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 10:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 22379.3928
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 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 22379.39285
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.

Step 12:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 22379.392857
Deduct 196 from 200 and we're left with 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 13:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 22379.3928571
Subtracting 28 from 40 leaves us 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.

Going ahead to step 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 22379.39285714
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.

In conclusion, the division gives 22379.39285714 with a balance of 8e-09.
