814186 ÷ 20 
We want to figure out the number of times 814186 can be divided by 20.

On to step 1:
20 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
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

Step 2:
20 goes into 81 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 80 away from 81, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Step 3:
The number 20 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 14, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 20

Moving on to step 4:
20 can be fit into 141 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 407.0
The remainder is 1 after subtracting 140 from 141.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 20

Going ahead to step 5:
20 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 4070.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 20

Advancing to step 6:
186 divided by 20 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 40709.0
Subtract 180 from 186 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 20, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 40709.3
Deduct 60 from 60 and we're left 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.

Moving on to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40709.3
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40709.3
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.

The final result is 40709.3 with a remainder of 0.0.
