We're dividing 485760 by 28 
We're looking to find how many times 28 goes into 485760.

Moving on to step 1:
4 divided by 28 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 28

Going ahead to step 2:
The number 28 fits into 48 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 28 from 48 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 28

On to step 3:
When dividing 205 by 28, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 196 from 205 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 28

Advancing to step 4:
28 goes into 97 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 173.0
The remainder is 13 after subtracting 84 from 97.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 28

Step 5:
136 divided by 28 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1734.0
If we take 112 away from 136, we end up with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 28

Step 6:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 17348.0
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.

Moving on to step 7:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 17348.5
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.

Advancing to step 8:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 17348.57
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.

Let's proceed to step 9:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 17348.571
Deduct 28 from 40 and we're left 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.

Let's proceed to step 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 17348.5714
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.

Let's proceed to step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 17348.57142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 17348.571428
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:
If we divide 160 by 28, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 17348.5714285
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.

Step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 17348.57142857
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.

Our division results in 17348.57142857 with a remaining 4e-09.
