454417 divided by 28 
The aim is to understand the frequency of 28 in 454417.

On to step 1:
The number 28 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 28

Going ahead to step 2:
When dividing 45 by 28, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 28 from 45 and we're left with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 28

Going ahead to step 3:
28 goes into 174 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 168 from 174 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 28

Let's proceed to step 4:
28 goes into 64 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 162.0
Subtracting 56 from 64 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 28

Moving on to step 5:
The number 28 fits into 81 2 times, leaving a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 1622.0
Subtracting 56 from 81 leaves us with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 28

On to step 6:
28 goes into 257 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 16229.0
Deduct 252 from 257 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 28 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 16229.1
If we subtract 28 from 50, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 28, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 16229.17
Subtract 196 from 220 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 16229.178
If we subtract 224 from 240, we 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.

Moving on to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 16229.1785
If we take 140 away from 160, we end up 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 11:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 16229.17857
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.

Moving on to step 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 16229.178571
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.

Moving on to step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 16229.1785714
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.

On to step 14:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16229.17857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 16229.17857142 and a remainder of 2.4e-08.
