We divide 865780 by 20
We're looking to find how many times 20 goes into 865780.

On to step 1:
8 divided by 20 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 20

Moving on to step 2:
When dividing 86 by 20, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 80 from 86 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 20

Going ahead to step 3:
If we divide 65 by 20, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Moving on to step 4:
57 divided by 20 is 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
Deduct 40 from 57 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 20

Moving on to step 5:
If we divide 178 by 20, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4328.0
The remainder is 18 after subtracting 160 from 178.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Advancing to step 6:
180 divided by 20 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 43289.0
If we take 180 away from 180, 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.

Going ahead to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43289.0
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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43289.0
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.

The final result is 43289.0 with a remainder of 0.0.
