We look at the division of 534380 by 28 
The aim is to understand the frequency of 28 in 534380.

Let's proceed to step 1:
5 divided by 28 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 28

Advancing to step 2:
When dividing 53 by 28, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 28 from 53 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 28

On to step 3:
If we divide 254 by 28, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 252 from 254 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 28

Step 4:
When dividing 23 by 28, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we subtract 0 from 23, we get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 28

Going ahead to step 5:
28 goes into 238 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1908.0
The remainder is 14 after subtracting 224 from 238.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 28

Advancing to step 6:
If we divide 140 by 28, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 19085.0
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.

Let's proceed to step 7:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 19085.0
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:
28 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19085.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 19085.0 and a remainder of 0.0.
