We look at the division of 815562 by 66 
Our goal is to divide 815562 by 66.

On to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 66

Going ahead to step 2:
When dividing 81 by 66, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 66 away from 81, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 66

Going ahead to step 3:
155 divided by 66 is 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 12.0
If we take 132 away from 155, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 66

Going ahead to step 4:
66 goes into 235 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 198 from 235 and we're left with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 66

Moving on to step 5:
376 divided by 66 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 1235.0
The remainder is 46 after subtracting 330 from 376.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 66

On to step 6:
66 can be fit into 462 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 12357.0
If we take 462 away from 462, 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.

Going ahead to step 7:
When dividing 0 by 66, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12357.0
Deduct 0 from 0 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.

Step 8:
When dividing 0 by 66, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12357.0
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.

The final result is 12357.0 with a remainder of 0.0.
