306717 ÷ 28 
We're looking to find how many times 28 goes into 306717.

Step 1:
28 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 28

Moving on to step 2:
28 goes into 30 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 28 from 30.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 28

Let's proceed to step 3:
The number 28 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 28

On to step 4:
The number 28 fits into 267 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 15 after subtracting 252 from 267.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 28

Going ahead to step 5:
28 can be fit into 151 5 times, resulting in a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
If we take 140 away from 151, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 28

Advancing to step 6:
28 goes into 117 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 10954.0
If we take 112 away from 117, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 28 fits into 50 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10954.1
Subtract 28 from 50 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 28, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 10954.17
If we take 196 away from 220, we end up 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.

Moving on to step 9:
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: 10954.178
If we take 224 away from 240, we end up 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.

Let's proceed to step 10:
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: 10954.1785
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.

Moving on to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 10954.17857
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 12:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 10954.178571
Subtracting 28 from 40 leaves us 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 13:
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: 10954.1785714
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 14:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10954.17857142
Subtracting 56 from 80 leaves us 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.

The quotient of the division is 10954.17857142, and the remainder is 2.4e-08.
