984231 ÷ 20 
We want to divide 984231 by 20.

Going ahead to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 20

Moving on to step 2:
The number 20 fits into 98 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 18 after subtracting 80 from 98.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 20

Moving on to step 3:
If we divide 184 by 20, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 180 from 184 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 20

Moving on to step 4:
The number 20 fits into 42 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
Subtract 40 from 42 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 20

Moving on to step 5:
20 can be fit into 23 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 4921.0
If we subtract 20 from 23, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

Moving on to step 6:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 49211.0
If we take 20 away from 31, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 49211.5
Subtracting 100 from 110 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49211.55
If we subtract 100 from 100, 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.

The final outcome is 49211.55, with a leftover of 0.0.
