We divide 814390 by 20
We're looking to find how many times 20 goes into 814390.

Going ahead to step 1:
8 divided by 20 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 20

On to step 2:
If we divide 81 by 20, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 80 from 81 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 20

Advancing to step 3:
If we divide 14 by 20, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 14 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 20

Step 4:
When dividing 143 by 20, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 407.0
The remainder is 3 after subtracting 140 from 143.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

On to step 5:
39 divided by 20 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4071.0
Subtract 20 from 39 to get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 20

Step 6:
20 goes into 190 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 40719.0
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40719.5
If we take 100 away from 100, 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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40719.5
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:
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: 40719.5
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.

The quotient of the division is 40719.5, and the remainder is 0.0.
