We divide 405790 by 28
The aim is to understand the frequency of 28 in 405790.

Let's proceed to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 28

Step 2:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 28 from 40.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 28

On to step 3:
28 goes into 125 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 13 after subtracting 112 from 125.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 28

Advancing to step 4:
The number 28 fits into 137 4 times, leaving a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtract 112 from 137 to get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 28

Let's proceed to step 5:
If we divide 259 by 28, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1449.0
If we subtract 252 from 259, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 28

Going ahead to step 6:
If we divide 70 by 28, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 14492.0
If we subtract 56 from 70, 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.

On to step 7:
140 divided by 28 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14492.5
Deduct 140 from 140 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.

On to step 8:
If we divide 0 by 28, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14492.5
The remainder is 0 after subtracting 0 from 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 9:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14492.5
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.

In conclusion, the division gives 14492.5 with a balance of 0.0.
