We look at the division of 480888 by 28 
The aim is to understand the frequency of 28 in 480888.

On to step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 28

Advancing to step 2:
The number 28 fits into 48 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 28 from 48 and we're left with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 28

Going ahead to step 3:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 17.0
If we take 196 away from 200, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 28

Moving on to step 4:
48 divided by 28 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Deduct 28 from 48 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 28

Step 5:
If we divide 208 by 28, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 1717.0
Subtract 196 from 208 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 28

Advancing to step 6:
128 divided by 28 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 17174.0
Deduct 112 from 128 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.

On to step 7:
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: 17174.5
Subtracting 140 from 160 leaves us 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.

Advancing to step 8:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 17174.57
Subtracting 196 from 200 leaves us 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.

On to step 9:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 17174.571
Deduct 28 from 40 and we're left 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 10:
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: 17174.5714
If we take 112 away from 120, 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.

Advancing to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 17174.57142
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.

Advancing to step 12:
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: 17174.571428
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.

Let's proceed to step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17174.5714285
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.

On to step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 17174.57142857
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.

The quotient of the division is 17174.57142857, and the remainder is 4e-09.
