173873 ÷ 28 
The aim is to understand the frequency of 28 in 173873.

Moving on to step 1:
The number 28 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 28

Step 2:
If we divide 17 by 28, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 28

Going ahead to step 3:
28 can be fit into 173 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 168 from 173 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 28

Advancing to step 4:
58 divided by 28 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 62.0
If we take 56 away from 58, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 28

Going ahead to step 5:
28 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 620.0
Subtract 0 from 27 to get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 28

Moving on to step 6:
28 can be fit into 273 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 6209.0
Subtract 252 from 273 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 28, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 6209.7
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6209.75
Subtracting 140 from 140 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.

Moving on to step 9:
If we divide 0 by 28, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6209.75
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.

Let's proceed to step 10:
0 divided by 28 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6209.75
Deduct 0 from 0 and we're left 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.

Our division results in 6209.75 with a remaining 0.0.
