We're dividing 778401 by 20 
Let's see how many times 20 fits into 778401.

Going ahead to step 1:
20 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 20

On to step 2:
20 can be fit into 77 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 77, we end up with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Going ahead to step 3:
178 divided by 20 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 160 from 178, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 20

Step 4:
184 divided by 20 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 389.0
Deduct 180 from 184 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Going ahead to step 5:
40 divided by 20 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3892.0
If we subtract 40 from 40, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 20

On to step 6:
1 divided by 20 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 38920.0
If we take 0 away from 1, we end up 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.

Moving on to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 38920.0
Subtracting 0 from 10 leaves us 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 38920.05
The remainder is 0 after subtracting 100 from 100.
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:
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: 38920.05
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.

Let's proceed 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: 38920.05
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.

In conclusion, the division gives 38920.05 with a balance of 0.0.
