We divide 778782 by 20
Our goal is to divide 778782 by 20.

Moving on to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 20

Step 2:
20 goes into 77 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 17 after subtracting 60 from 77.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 20

Moving on to step 3:
20 goes into 178 8 times with 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.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

On to step 4:
The number 20 fits into 187 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 389.0
If we take 180 away from 187, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Step 5:
When dividing 78 by 20, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3893.0
If we subtract 60 from 78, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 20

On to step 6:
The number 20 fits into 182 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 38939.0
If we subtract 180 from 182, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 38939.1
If we take 20 away from 20, 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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38939.1
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38939.1
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 outcome is 38939.1, with a leftover of 0.0.
