We look at the division of 349804 by 20 
We want to figure out the number of times 349804 can be divided by 20.

Step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 20

Step 2:
34 divided by 20 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 20 from 34 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 20

Moving on to step 3:
When dividing 149 by 20, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 9 after subtracting 140 from 149.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 20

Let's proceed to step 4:
When dividing 98 by 20, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 174.0
If we take 80 away from 98, we end up with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 20

On to step 5:
If we divide 180 by 20, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 1749.0
If we subtract 180 from 180, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 20

Let's proceed to step 6:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 17490.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 20, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 17490.2
If we take 40 away from 40, 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.

On to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17490.2
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17490.2
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 17490.2 and a remainder of 0.0.
