52878 ÷ 28 
The aim is to understand the frequency of 28 in 52878.

Let's proceed to step 1:
28 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 28

Going ahead to step 2:
The number 28 fits into 52 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 24 after subtracting 28 from 52.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 28

Step 3:
When dividing 248 by 28, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 224 from 248 and we're left with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 28

Moving on to step 4:
If we divide 247 by 28, we get 8 and a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 224 from 247 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 28

Let's proceed to step 5:
If we divide 238 by 28, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 1888.0
If we subtract 224 from 238, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
When dividing 140 by 28, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1888.5
The remainder is 0 after subtracting 140 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 28, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1888.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1888.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1888.5 and a remainder of 0.0.
