We divide 648103 by 28
Let's see how many times 28 fits into 648103.

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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 28

Going ahead to step 2:
When dividing 64 by 28, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 56 from 64 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 28

Advancing to step 3:
If we divide 88 by 28, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 84 away from 88, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 28

Going ahead to step 4:
28 goes into 41 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 231.0
Subtract 28 from 41 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 28

Moving on to step 5:
28 goes into 130 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 2314.0
The remainder is 18 after subtracting 112 from 130.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 28

Step 6:
When dividing 183 by 28, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 23146.0
If we take 168 away from 183, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
28 goes into 150 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23146.5
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
28 can be fit into 100 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 23146.53
If we subtract 84 from 100, 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 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 23146.535
If we take 140 away from 160, we end up 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.

Let's proceed to step 10:
200 divided by 28 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 23146.5357
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.

Going ahead to step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 23146.53571
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.

Step 12:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 23146.535714
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 23146.5357142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 23146.53571428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 23146.53571428 with a remainder of 1.6e-08.
