We divide 989455 by 20
We're looking to find how many times 20 goes into 989455.

Going ahead to step 1:
If we divide 9 by 20, we get 0 and 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.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 20

Let's proceed to step 2:
When dividing 98 by 20, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 80 away from 98, we end up with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 20

Going ahead to step 3:
20 goes into 189 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtracting 180 from 189 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 20

Advancing to step 4:
20 goes into 94 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we subtract 80 from 94, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 20

Step 5:
20 goes into 145 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 4947.0
If we subtract 140 from 145, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 20

Step 6:
20 can be fit into 55 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 49472.0
If we subtract 40 from 55, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 49472.7
If we take 140 away from 150, 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 49472.75
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49472.75
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.

Step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49472.75
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.

In conclusion, the division gives 49472.75 with a balance of 0.0.
