66 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 66

Moving on to step 3:
If we divide 370 by 66, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 40 after subtracting 330 from 370.

Going ahead to step 9:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 5608.469
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 66, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 5608.4696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 5608.46969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
460 divided by 66 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 5608.469696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 5608.4696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 66, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 5608.46969696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.
