8630 divided by 28 
Our goal is to divide 8630 by 28.

Moving on to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 28

Let's proceed to step 2:
28 can be fit into 86 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 84 from 86 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 28

Advancing to step 3:
23 divided by 28 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 28

Advancing to step 4:
The number 28 fits into 230 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 308.0
If we take 224 away from 230, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 5:
If we divide 60 by 28, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 308.2
Deduct 56 from 60 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.

On to step 6:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 308.21
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 308.214
Subtract 112 from 120 to 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.

On to step 8:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 308.2142
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.

Let's proceed to step 9:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 308.21428
Subtracting 224 from 240 leaves us 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.

Going ahead to step 10:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 308.214285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 308.2142857
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.

Advancing to step 12:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 308.21428571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 308.21428571 with a balance of 1.2e-08.
