449213 divided by 28 
The aim is to understand the frequency of 28 in 449213.

Let's proceed to step 1:
4 divided by 28 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 28

Going ahead to step 2:
If we divide 44 by 28, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 28 from 44 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 28

Let's proceed to step 3:
169 divided by 28 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 1 after subtracting 168 from 169.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 28

Going ahead to step 4:
28 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 28

Going ahead to step 5:
28 goes into 121 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
Subtract 112 from 121 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 28

Going ahead to step 6:
If we divide 93 by 28, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 16043.0
The remainder is 9 after subtracting 84 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 28, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 16043.3
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:
28 goes into 60 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16043.32
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.

Moving on to step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 16043.321
Subtract 28 from 40 to 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.

On to step 10:
120 divided by 28 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 16043.3214
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.

Let's proceed to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 16043.32142
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.

Step 12:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 16043.321428
Subtracting 224 from 240 leaves us 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.

Let's proceed to step 13:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 16043.3214285
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.

On to step 14:
200 divided by 28 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 16043.32142857
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 result is 16043.32142857 with a remainder of 4e-09.
