We look at the division of 306320 by 28 
We're looking to find how many times 28 goes into 306320.

Step 1:
28 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 28

Step 2:
If we divide 30 by 28, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 28 from 30 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 28

Advancing to step 3:
28 goes into 26 0 times with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 26, we end up with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 28

Let's proceed to step 4:
28 goes into 263 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
If we take 252 away from 263, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 28

Let's proceed to step 5:
When dividing 112 by 28, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
Subtracting 112 from 112 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 28

Let's proceed to step 6:
When dividing 0 by 28, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10940.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 28, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10940.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10940.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10940.0 with a balance of 0.0.
