We divide 429935 by 20
We want to divide 429935 by 20.

On to step 1:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Moving on to step 2:
42 divided by 20 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 42 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 20

Advancing to step 3:
When dividing 29 by 20, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 20 from 29 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 20

Let's proceed to step 4:
99 divided by 20 is 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 214.0
Subtracting 80 from 99 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 20

Moving on to step 5:
20 can be fit into 193 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 2149.0
Subtracting 180 from 193 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 20

Going ahead to step 6:
135 divided by 20 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 21496.0
Deduct 120 from 135 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 21496.7
If we take 140 away from 150, we end up 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.

Moving on to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21496.75
Subtract 100 from 100 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21496.75
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.

Moving on to step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21496.75
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.

In conclusion, the division gives 21496.75 with a balance of 0.0.
