492231 ÷ 20 
Let's see how many times 20 fits into 492231.

Let's proceed to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 20

On to step 2:
20 can be fit into 49 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 40 from 49 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 20

Step 3:
When dividing 92 by 20, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 12 after subtracting 80 from 92.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 20

Step 4:
122 divided by 20 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 246.0
Deduct 120 from 122 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 20

Going ahead to step 5:
20 goes into 23 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 2461.0
The remainder is 3 after subtracting 20 from 23.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

Going ahead to step 6:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 24611.0
Deduct 20 from 31 and we're left 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.

Step 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 24611.5
If we take 100 away from 110, 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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 24611.55
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 result is 24611.55 with a remainder of 0.0.
