660928 ÷ 28 
We're looking to find how many times 28 goes into 660928.

Let's proceed to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 28

Advancing to step 2:
28 goes into 66 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 56 from 66, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 28

Advancing to step 3:
If we divide 100 by 28, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 84 from 100 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 28

Let's proceed to step 4:
The number 28 fits into 169 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 236.0
Deduct 168 from 169 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 28

On to step 5:
If we divide 12 by 28, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 2360.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 28

On to step 6:
28 goes into 128 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 23604.0
Subtract 112 from 128 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:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 23604.5
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.

On to step 8:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 23604.57
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.

On to step 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 23604.571
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.

Advancing to step 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 23604.5714
The remainder is 8 after subtracting 112 from 120.
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 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 23604.57142
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.

Step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 23604.571428
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.

Advancing to step 13:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 23604.5714285
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.
Write down 7 as next digit of the result. 
Result so far: 23604.57142857
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.

The final outcome is 23604.57142857, with a leftover of 4e-09.
