We're dividing 30113 by 20 
Let's see how many times 20 fits into 30113.

Let's proceed to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Step 2:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 20 from 30 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 20

Going ahead to step 3:
The number 20 fits into 101 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 100 away from 101, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 20

Advancing to step 4:
When dividing 11 by 20, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 20

Step 5:
The number 20 fits into 113 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 1505.0
Subtract 100 from 113 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 6:
When dividing 130 by 20, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1505.6
If we subtract 120 from 130, 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.

On to step 7:
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: 1505.65
If we take 100 away from 100, 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.

Going ahead to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1505.65
Subtracting 0 from 0 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.

Step 9:
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: 1505.65
The remainder is 0 after subtracting 0 from 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 1505.65 with a remainder of 0.0.
