We're dividing 81215030 by 165 
We're looking to find how many times 165 goes into 81215030.

Moving on to step 1:
The number 165 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 165

On to step 2:
If we divide 81 by 165, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 165

Going ahead to step 3:
812 divided by 165 is 4 with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 660 away from 812, we end up with 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 165

Going ahead to step 4:
If we divide 1521 by 165, we get 9 and a remainder of 36.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 1485 from 1521 to get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 165

Going ahead to step 5:
165 goes into 365 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 492.0
If we take 330 away from 365, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 165

Step 6:
When dividing 350 by 165, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 4922.0
The remainder is 20 after subtracting 330 from 350.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 165

Going ahead to step 7:
165 goes into 203 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 49221.0
If we take 165 away from 203, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 165

Step 8:
The number 165 fits into 380 2 times, leaving a remainder of 50.
The next digit of our result is 2. 
Result so far: 492212.0
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
165 can be fit into 500 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 492212.3
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
The number 165 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 492212.3
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 165 fits into 500 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 492212.303
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
If we divide 50 by 165, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 492212.303
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
500 divided by 165 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 492212.30303
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
The number 165 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 492212.30303
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
When dividing 500 by 165, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 492212.3030303
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 16:
If we divide 50 by 165, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 492212.3030303
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 492212.3030303, and the remainder is 5e-08.
