We're dividing 998736 by 20 
Let's see how many times 20 fits into 998736.

Step 1:
9 divided by 20 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

Let's proceed to step 2:
The number 20 fits into 99 4 times, leaving a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 80 from 99 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 20

Step 3:
When dividing 198 by 20, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 180 away from 198, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

Going ahead to step 4:
20 can be fit into 187 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 499.0
If we take 180 away from 187, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 20

Let's proceed to step 5:
20 goes into 73 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 4993.0
If we take 60 away from 73, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 20

On to step 6:
If we divide 136 by 20, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 49936.0
If we take 120 away from 136, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 20, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 49936.8
Subtracting 160 from 160 leaves us 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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49936.8
Subtract 0 from 0 to 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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49936.8
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.

In conclusion, the division gives 49936.8 with a balance of 0.0.
