We divide 998916 by 20
We're looking to find how many times 20 goes into 998916.

Going ahead to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

On to step 2:
If we divide 99 by 20, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 80 away from 99, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 20

Let's proceed to step 3:
If we divide 198 by 20, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 180 away from 198, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 20

On to step 4:
When dividing 189 by 20, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
Subtract 180 from 189 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Let's proceed to step 5:
If we divide 91 by 20, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 4994.0
Subtract 80 from 91 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 20

Let's proceed to step 6:
20 can be fit into 116 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 49945.0
The remainder is 16 after subtracting 100 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 20 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 49945.8
The remainder is 0 after subtracting 160 from 160.
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:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49945.8
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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 49945.8
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.

The final outcome is 49945.8, with a leftover of 0.0.
