340557 ÷ 28 
We're looking to find how many times 28 goes into 340557.

On to step 1:
28 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 28

Let's proceed to step 2:
28 can be fit into 34 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 28 from 34 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 28

On to step 3:
60 divided by 28 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 56 from 60, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 28

Step 4:
When dividing 45 by 28, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 28 from 45, we get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 28

On to step 5:
28 goes into 175 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 1216.0
Subtracting 168 from 175 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 28

Let's proceed to step 6:
28 can be fit into 77 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12162.0
The remainder is 21 after subtracting 56 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to 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: 12162.7
If we take 196 away from 210, we end up 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.

Going ahead 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: 12162.75
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.

Let's proceed to step 9:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12162.75
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.

Step 10:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12162.75
Subtract 0 from 0 to get 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 12162.75 with a remainder of 0.0.
