Let's divide 648789 by 66
Let's see how many times 66 fits into 648789.

Step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 66

Step 2:
If we divide 64 by 66, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 66

Moving on to step 3:
When dividing 648 by 66, we get 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 594 from 648 to get 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 66

On to step 4:
66 goes into 547 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 528 from 547, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 66

Let's proceed to step 5:
When dividing 198 by 66, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 983.0
Subtract 198 from 198 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 66

Step 6:
If we divide 9 by 66, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 9830.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 66, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 9830.1
Subtract 66 from 90 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 8:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9830.13
Deduct 198 from 240 and we're left 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.

Advancing to step 9:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 9830.136
If we subtract 396 from 420, we 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.

On to step 10:
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: 9830.1363
If we take 198 away from 240, we end up 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 11:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 9830.13636
Deduct 396 from 420 and we're left with 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 12:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 9830.136363
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.

Advancing to step 13:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 9830.1363636
Subtracting 396 from 420 leaves us with 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 14:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 9830.13636363
If we take 198 away from 240, we end up 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.

The final result is 9830.13636363 with a remainder of 4.2e-08.
