We divide 449986 by 20
We're looking to find how many times 20 goes into 449986.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

On to step 2:
44 divided by 20 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 44 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 20

Moving on to step 3:
The number 20 fits into 49 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 40 from 49 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

On to step 4:
20 goes into 99 4 times with a remainder of 19.
The next digit of our result is 4. 
Result so far: 224.0
If we take 80 away from 99, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 20

Let's proceed to step 5:
When dividing 198 by 20, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 2249.0
If we take 180 away from 198, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 20

On to step 6:
20 goes into 186 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 22499.0
Deduct 180 from 186 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 20 fits into 60 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 22499.3
Deduct 60 from 60 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.

Let's proceed to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22499.3
Deduct 0 from 0 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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22499.3
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 quotient of the division is 22499.3, and the remainder is 0.0.
