404997 divided by 20 
We want to divide 404997 by 20.

Moving on 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
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 20

Step 2:
When dividing 40 by 20, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 40 from 40.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 20

Advancing to step 3:
When dividing 4 by 20, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 20

Step 4:
20 goes into 49 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Deduct 40 from 49 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 20

On to step 5:
The number 20 fits into 99 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 2024.0
Subtract 80 from 99 to get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 20

Moving on to step 6:
197 divided by 20 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 20249.0
If we take 180 away from 197, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 20249.8
Deduct 160 from 170 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.

On to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20249.85
Deduct 100 from 100 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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20249.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20249.85
If we take 0 away from 0, we end up 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 20249.85 with a remainder of 0.0.
