661395 ÷ 28 
Let's see how many times 28 fits into 661395.

Moving on to step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 28

On to step 2:
When dividing 66 by 28, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 66 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 28

Moving on to step 3:
If we divide 101 by 28, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 17 after subtracting 84 from 101.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 28

On to step 4:
When dividing 173 by 28, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 236.0
If we take 168 away from 173, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 28

Moving on to step 5:
28 can be fit into 59 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2362.0
Deduct 56 from 59 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 28

Going ahead to step 6:
The number 28 fits into 35 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 23621.0
If we take 28 away from 35, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
28 can be fit into 70 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 23621.2
Deduct 56 from 70 and we're left 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:
If we divide 140 by 28, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23621.25
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.

Let's proceed to step 9:
When dividing 0 by 28, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23621.25
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.

Step 10:
0 divided by 28 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23621.25
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 quotient of the division is 23621.25, and the remainder is 0.0.
