We're dividing 780068 by 20 
Let's see how many times 20 fits into 780068.

Step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Let's proceed to step 2:
The number 20 fits into 78 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 78 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Step 3:
If we divide 180 by 20, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 180 from 180 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 20

Moving on to step 4:
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: 390.0
If we take 0 away from 0, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 20

Advancing to step 5:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 3900.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Moving on to step 6:
68 divided by 20 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 39003.0
If we take 60 away from 68, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
20 goes into 80 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 39003.4
Subtract 80 from 80 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.

On to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39003.4
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.

Going ahead 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: 39003.4
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 39003.4, and the remainder is 0.0.
