We're dividing 302683 by 20 
We want to divide 302683 by 20.

Step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

On to step 2:
When dividing 30 by 20, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 20 from 30 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 20

Step 3:
The number 20 fits into 102 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 100 from 102 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 20

Let's proceed to step 4:
26 divided by 20 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we take 20 away from 26, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

On to step 5:
20 goes into 68 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 1513.0
Subtracting 60 from 68 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 20

Going ahead to step 6:
The number 20 fits into 83 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 15134.0
If we subtract 80 from 83, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 15134.1
The remainder is 10 after subtracting 20 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15134.15
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15134.15
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15134.15
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 15134.15 with a balance of 0.0.
