Let's divide 306781 by 20
We want to divide 306781 by 20.

Going ahead to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 20

Going ahead to step 2:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 30, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 20

Step 3:
20 can be fit into 106 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 100 from 106 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 20

Let's proceed to step 4:
The number 20 fits into 67 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 60 from 67 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Let's proceed to step 5:
78 divided by 20 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 1533.0
Subtracting 60 from 78 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 20

Advancing to step 6:
When dividing 181 by 20, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 15339.0
Subtracting 180 from 181 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 20, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15339.0
Deduct 0 from 10 and we're left 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.

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: 15339.05
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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15339.05
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.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15339.05
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.

Our division results in 15339.05 with a remaining 0.0.
