We look at the division of 330938 by 20 
We want to figure out the number of times 330938 can be divided by 20.

Step 1:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 20

On to step 2:
33 divided by 20 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 20 from 33, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 20

Going ahead to step 3:
If we divide 130 by 20, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 120 from 130, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 20

Let's proceed to step 4:
20 can be fit into 109 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we subtract 100 from 109, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 20

On to step 5:
When dividing 93 by 20, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 1654.0
If we take 80 away from 93, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 20

Moving on to step 6:
When dividing 138 by 20, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 16546.0
Deduct 120 from 138 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 20, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 16546.9
Deduct 180 from 180 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16546.9
Subtract 0 from 0 to get 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16546.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 16546.9 and a remainder of 0.0.
