We're dividing 454311 by 28 
The aim is to understand the frequency of 28 in 454311.

On to step 1:
28 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 28

Advancing to step 2:
The number 28 fits into 45 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 28 from 45 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 28

On to step 3:
When dividing 174 by 28, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 168 from 174 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 28

Moving on to step 4:
The number 28 fits into 63 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 56 from 63 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 28

Advancing to step 5:
71 divided by 28 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 1622.0
Subtracting 56 from 71 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 28

Let's proceed to step 6:
28 can be fit into 151 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 16225.0
Subtract 140 from 151 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.

Let's proceed to step 7:
28 goes into 110 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 16225.3
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.

Let's proceed to step 8:
When dividing 260 by 28, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 16225.39
Subtract 252 from 260 to 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.

Step 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16225.392
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.

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: 16225.3928
If we take 224 away from 240, we end up 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 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 16225.39285
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 12:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 16225.392857
If we take 196 away from 200, we end up 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.

Going ahead to step 13:
When dividing 40 by 28, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 16225.3928571
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 14:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 16225.39285714
Subtracting 112 from 120 leaves us 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.

Our division results in 16225.39285714 with a remaining 8e-09.
