We divide 646791 by 66
Our goal is to divide 646791 by 66.

Advancing to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 66

Step 2:
When dividing 64 by 66, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 66

Step 3:
66 can be fit into 646 9 times, resulting in a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 594 from 646 and we're left with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 66

Advancing to step 4:
66 goes into 527 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 462 from 527, we get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 66

Step 5:
659 divided by 66 is 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 979.0
Deduct 594 from 659 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 66

Going ahead to step 6:
66 can be fit into 651 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 9799.0
If we take 594 away from 651, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 66, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 9799.8
Subtract 528 from 570 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9799.86
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9799.863
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
66 goes into 420 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 9799.8636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 9799.86363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
66 goes into 420 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9799.863636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9799.8636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9799.86363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 9799.86363636, and the remainder is 2.4e-08.
