We look at the division of 18644 by 28 
We're looking to find how many times 28 goes into 18644.

On to step 1:
1 divided by 28 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 28

Step 2:
When dividing 18 by 28, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 28

Advancing to step 3:
If we divide 186 by 28, we get 6 and a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 168 away from 186, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 28

Moving on to step 4:
28 goes into 184 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 16 after subtracting 168 from 184.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 28

Let's proceed to step 5:
28 can be fit into 164 5 times, resulting in a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Deduct 140 from 164 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.

Step 6:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 665.8
Subtract 224 from 240 to 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.

On to step 7:
28 goes into 160 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 665.85
Subtract 140 from 160 to 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.

Moving on to step 8:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 665.857
Subtract 196 from 200 to 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 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 665.8571
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.

Advancing to step 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 665.85714
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 number 2 becomes the next digit in our result. 
Result so far: 665.857142
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.

Step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 665.8571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 665.85714285
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.

Our division results in 665.85714285 with a remaining 2e-08.
