811566 divided by 28 
We're looking to find how many times 28 goes into 811566.

Step 1:
8 divided by 28 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 28

Advancing to step 2:
When dividing 81 by 28, we get 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 56 from 81 leaves us with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 28

Let's proceed to step 3:
If we divide 251 by 28, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 27 after subtracting 224 from 251.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 28

Let's proceed to step 4:
The number 28 fits into 275 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
Deduct 252 from 275 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 28

On to step 5:
The number 28 fits into 236 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2898.0
Subtracting 224 from 236 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 28

Advancing to step 6:
If we divide 126 by 28, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 28984.0
If we subtract 112 from 126, 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:
28 goes into 140 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 28984.5
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 8:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28984.5
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.

Advancing to step 9:
28 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28984.5
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.

The final result is 28984.5 with a remainder of 0.0.
