812181 divided by 36 
We want to figure out the number of times 812181 can be divided by 36.

Let's proceed to step 1:
36 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 36

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
If we take 72 away from 81, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 36

Let's proceed to step 3:
If we divide 92 by 36, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 72 from 92 and we're left with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 36

Going ahead to step 4:
The number 36 fits into 201 5 times, leaving a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 225.0
The remainder is 21 after subtracting 180 from 201.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 36

On to step 5:
36 goes into 218 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2256.0
The remainder is 2 after subtracting 216 from 218.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 36

Advancing to step 6:
36 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 22560.0
If we take 0 away from 21, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 36, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 22560.5
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 22560.58
If we take 288 away from 300, we end up 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 9:
The number 36 fits into 120 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 22560.583
If we take 108 away from 120, we end up 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.

Advancing to step 10:
120 divided by 36 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 22560.5833
Deduct 108 from 120 and we're left 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.

After the division, we end up with 22560.5833 and a remainder of 0.00012.
