We're dividing 778773 by 20 
We want to figure out the number of times 778773 can be divided by 20.

On to step 1:
20 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 20

Moving on to step 2:
77 divided by 20 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 77, we get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 20

Advancing to step 3:
If we divide 178 by 20, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 160 from 178 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

Let's proceed to step 4:
The number 20 fits into 187 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 389.0
Deduct 180 from 187 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 20

Let's proceed to step 5:
77 divided by 20 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3893.0
Deduct 60 from 77 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 20

Advancing to step 6:
173 divided by 20 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 38938.0
Subtracting 160 from 173 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 38938.6
Deduct 120 from 130 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.

Going ahead to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 38938.65
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38938.65
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.

Let's proceed to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38938.65
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.

In conclusion, the division gives 38938.65 with a balance of 0.0.
