985309 divided by 20 
Our goal is to divide 985309 by 20.

Moving on to step 1:
The number 20 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 20

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
If we subtract 80 from 98, we get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 20

Advancing to step 3:
20 can be fit into 185 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 49.0
If we take 180 away from 185, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Advancing to step 4:
The number 20 fits into 53 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 492.0
If we subtract 40 from 53, we get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 20

Going ahead to step 5:
20 goes into 130 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4926.0
The remainder is 10 after subtracting 120 from 130.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 20

Advancing to step 6:
The number 20 fits into 109 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 49265.0
If we subtract 100 from 109, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 20, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 49265.4
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 49265.45
Subtract 100 from 100 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:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49265.45
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 49265.45
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 result is 49265.45 with a remainder of 0.0.
