Let's divide 430984 by 20
We want to figure out the number of times 430984 can be divided by 20.

Moving on to step 1:
4 divided by 20 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Moving on to step 2:
43 divided by 20 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 43 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 20

On to step 3:
The number 20 fits into 30 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 20 from 30, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 20

Moving on to step 4:
The number 20 fits into 109 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 215.0
Deduct 100 from 109 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Step 5:
20 goes into 98 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 2154.0
If we subtract 80 from 98, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 20

Advancing to step 6:
The number 20 fits into 184 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 21549.0
Subtract 180 from 184 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 21549.2
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

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: 21549.2
If we subtract 0 from 0, we 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.

Moving on 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: 21549.2
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.

The final result is 21549.2 with a remainder of 0.0.
