815286 ÷ 36 
Our goal is to divide 815286 by 36.

On to step 1:
36 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 36

Advancing to step 2:
The number 36 fits into 81 2 times, leaving a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 9 after subtracting 72 from 81.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 36

Step 3:
The number 36 fits into 95 2 times, leaving a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 72 away from 95, we end up with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 36

Advancing to step 4:
36 goes into 232 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 226.0
Subtract 216 from 232 to get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 36

Advancing to step 5:
If we divide 168 by 36, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 2264.0
If we subtract 144 from 168, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 36

Step 6:
36 can be fit into 246 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 22646.0
If we subtract 216 from 246, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 22646.8
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 36, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 22646.83
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 36, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 22646.833
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 22646.833 and a remainder of 0.0012.
