We look at the division of 645408 by 66 
We want to divide 645408 by 66.

Let's proceed to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 66

Moving on to step 2:
When dividing 64 by 66, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 66

Moving on to step 3:
If we divide 645 by 66, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 51 after subtracting 594 from 645.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 66

Going ahead to step 4:
The number 66 fits into 514 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 462 from 514, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 66

Step 5:
520 divided by 66 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 977.0
Subtract 462 from 520 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 66

Going ahead to step 6:
When dividing 588 by 66, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 9778.0
If we take 528 away from 588, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9778.9
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 66, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9778.9
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9778.909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 9778.909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9778.90909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
66 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9778.90909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9778.9090909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9778.9090909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 9778.9090909, and the remainder is 6e-08.
