We divide 349945 by 20
We want to figure out the number of times 349945 can be divided by 20.

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
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 20

Let's proceed to step 2:
34 divided by 20 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 34 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 20

Going ahead to step 3:
When dividing 149 by 20, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 140 away from 149, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 20

Step 4:
20 goes into 99 4 times with a remainder of 19.
The next digit of our result is 4. 
Result so far: 174.0
If we take 80 away from 99, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

Advancing to step 5:
194 divided by 20 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 1749.0
If we take 180 away from 194, we end up with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 20

Step 6:
When dividing 145 by 20, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 17497.0
Deduct 140 from 145 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 20, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 17497.2
Subtracting 40 from 50 leaves us with 10.
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: 17497.25
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:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17497.25
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17497.25
The remainder is 0 after subtracting 0 from 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 17497.25 with a balance of 0.0.
