We divide 816800 by 66
We're looking to find how many times 66 goes into 816800.

Moving on to step 1:
8 divided by 66 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 66

Going ahead to step 2:
66 can be fit into 81 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 66 from 81 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 66

Going ahead to step 3:
156 divided by 66 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 132 from 156, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 66

On to step 4:
66 goes into 248 3 times with a remainder of 50.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 50 after subtracting 198 from 248.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 66

Let's proceed to step 5:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 1237.0
If we take 462 away from 500, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 66

Let's proceed to step 6:
If we divide 380 by 66, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12375.0
Subtracting 330 from 380 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.

Step 7:
500 divided by 66 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 12375.7
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
66 goes into 380 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12375.75
Subtract 330 from 380 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.

On to step 9:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 12375.757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12375.7575
Subtract 330 from 380 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.

On to step 11:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 12375.75757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
When dividing 380 by 66, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 12375.757575
If we subtract 330 from 380, we 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.

On to step 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 12375.7575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
When dividing 380 by 66, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12375.75757575
Subtract 330 from 380 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.

In conclusion, the division gives 12375.75757575 with a balance of 5e-08.
