We look at the division of 390624 by 66 
Let's see how many times 66 fits into 390624.

Moving on to step 1:
3 divided by 66 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 66

Moving on to step 2:
66 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 66

Going ahead to step 3:
390 divided by 66 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 330 from 390 to get 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 66

Going ahead to step 4:
66 goes into 606 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 59.0
Subtracting 594 from 606 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 66

On to step 5:
The number 66 fits into 122 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 591.0
Deduct 66 from 122 and we're left with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 66

Let's proceed to step 6:
66 goes into 564 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5918.0
If we take 528 away from 564, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
When dividing 360 by 66, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5918.5
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 66, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 5918.54
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5918.545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 5918.5454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
66 goes into 360 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5918.54545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5918.545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5918.5454545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5918.54545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 5918.54545454, and the remainder is 3.6e-08.
