We're dividing 645225 by 28 
We want to figure out the number of times 645225 can be divided by 28.

Let's proceed to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 28

Advancing to step 2:
64 divided by 28 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 56 from 64 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 28

Let's proceed to step 3:
28 can be fit into 85 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 84 from 85, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

Step 4:
28 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 230.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 28

Advancing to step 5:
The number 28 fits into 122 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 2304.0
Subtract 112 from 122 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 28

Going ahead to step 6:
105 divided by 28 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 23043.0
If we take 84 away from 105, we end up with 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:
When dividing 210 by 28, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 23043.7
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.

Let's proceed to step 8:
When dividing 140 by 28, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 23043.75
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.

Advancing 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: 23043.75
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.

Going ahead to step 10:
0 divided by 28 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23043.75
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.

In conclusion, the division gives 23043.75 with a balance of 0.0.
