We look at the division of 816548 by 66 
Our goal is to divide 816548 by 66.

Advancing to step 1:
8 divided by 66 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 66

Step 2:
66 goes into 81 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 66 from 81 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 66

On to step 3:
The number 66 fits into 156 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 132 from 156 to get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 66

On to step 4:
66 goes into 245 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 198 from 245 leaves us with 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 66

Step 5:
The number 66 fits into 474 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
If we subtract 462 from 474, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 66

Moving on to step 6:
The number 66 fits into 128 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 12371.0
If we take 66 away from 128, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 12371.9
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
260 divided by 66 is 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12371.93
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
620 divided by 66 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 12371.939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 12371.9393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
620 divided by 66 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 12371.93939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12371.939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 12371.9393939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12371.93939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.
