816185 divided by 40 
Our goal is to divide 816185 by 40.

Let's proceed to step 1:
8 divided by 40 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 40

Moving on to step 2:
The number 40 fits into 81 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 80 from 81 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 40

On to step 3:
16 divided by 40 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 16, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 40

Let's proceed to step 4:
When dividing 161 by 40, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
The remainder is 1 after subtracting 160 from 161.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 40

On to step 5:
If we divide 18 by 40, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 2040.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 40

Step 6:
185 divided by 40 is 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 20404.0
The remainder is 25 after subtracting 160 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
The number 40 fits into 250 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 20404.6
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 20404.62
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20404.625
If we take 200 away from 200, 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.

On to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20404.625
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.

On to step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20404.625
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 20404.625, with a leftover of 0.0.
