429395 ÷ 20 
Let's see how many times 20 fits into 429395.

Moving on to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 20

Step 2:
42 divided by 20 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 40 from 42, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

Moving on to step 3:
The number 20 fits into 29 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 20 from 29 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 20

Let's proceed to step 4:
The number 20 fits into 93 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we take 80 away from 93, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 20

On to step 5:
If we divide 139 by 20, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 2146.0
The remainder is 19 after subtracting 120 from 139.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

Step 6:
When dividing 195 by 20, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 21469.0
The remainder is 15 after subtracting 180 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 21469.7
Deduct 140 from 150 and we're left 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21469.75
The remainder is 0 after subtracting 100 from 100.
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 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21469.75
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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21469.75
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 outcome is 21469.75, with a leftover of 0.0.
