Let's divide 980830 by 20
Let's see how many times 20 fits into 980830.

Let's proceed to step 1:
9 divided by 20 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 20

Going ahead to step 2:
The number 20 fits into 98 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 80 from 98 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Moving on to step 3:
When dividing 180 by 20, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 180 from 180, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 20

Step 4:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Advancing to step 5:
20 can be fit into 83 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4904.0
Deduct 80 from 83 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 20

Step 6:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 49041.0
Subtract 20 from 30 to 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.

Advancing to step 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 49041.5
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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 49041.5
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 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49041.5
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.

The quotient of the division is 49041.5, and the remainder is 0.0.
