663854 divided by 28 
Our goal is to divide 663854 by 28.

Let's proceed to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 28

Let's proceed to step 2:
28 goes into 66 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 56 from 66, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 28

Moving on to step 3:
28 can be fit into 103 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 84 from 103 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 28

Advancing to step 4:
28 can be fit into 198 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 237.0
If we subtract 196 from 198, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 28

Moving on to step 5:
28 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 2370.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 28

Let's proceed to step 6:
28 goes into 254 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 23709.0
Deduct 252 from 254 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 28 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 23709.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 23709.07
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 23709.071
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
28 goes into 120 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 23709.0714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 23709.07142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 23709.071428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 23709.0714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 23709.07142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 23709.07142857 with a remainder of 4e-09.
