We look at the division of 981509 by 20 
We're looking to find how many times 20 goes into 981509.

Moving on to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Advancing to step 2:
98 divided by 20 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 18 after subtracting 80 from 98.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

Step 3:
If we divide 181 by 20, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 180 from 181 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

Advancing to step 4:
20 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 490.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Going ahead to step 5:
150 divided by 20 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 4907.0
If we take 140 away from 150, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 20

Going ahead to step 6:
20 can be fit into 109 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 49075.0
If we take 100 away from 109, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 49075.4
If we subtract 80 from 90, we get 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 49075.45
If we subtract 100 from 100, 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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49075.45
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 49075.45
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 49075.45, with a leftover of 0.0.
