Let's divide 328403 by 20
We want to figure out the number of times 328403 can be divided by 20.

Going ahead to step 1:
20 can be fit into 3 0 times, resulting in 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.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 20

Moving on to step 2:
If we divide 32 by 20, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 32 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 20

On to step 3:
128 divided by 20 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 120 from 128 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

On to step 4:
20 goes into 84 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Subtract 80 from 84 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Let's proceed to step 5:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1642.0
Subtracting 40 from 40 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 20

Going ahead to step 6:
3 divided by 20 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 16420.0
If we subtract 0 from 3, 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.

Let's proceed to step 7:
If we divide 30 by 20, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 16420.1
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 16420.15
If we subtract 100 from 100, 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.

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: 16420.15
If we take 0 away from 0, we end up 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 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16420.15
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.

After the division, we end up with 16420.15 and a remainder of 0.0.
