334389 divided by 20 
We're looking to find how many times 20 goes into 334389.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 20

On to step 2:
20 goes into 33 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 20 from 33.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 20

Advancing to step 3:
20 can be fit into 134 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 120 from 134, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

On to step 4:
The number 20 fits into 143 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
If we take 140 away from 143, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 20

On to step 5:
20 goes into 38 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1671.0
If we take 20 away from 38, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 20

Moving on to step 6:
20 can be fit into 189 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 16719.0
The remainder is 9 after subtracting 180 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 16719.4
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16719.45
If we take 100 away from 100, 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16719.45
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.

Let's proceed to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16719.45
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.

The final result is 16719.45 with a remainder of 0.0.
