390368 ÷ 66 
Our goal is to divide 390368 by 66.

Step 1:
3 divided by 66 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 66

Going ahead to step 2:
39 divided by 66 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 66

Going ahead to step 3:
66 goes into 390 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 330 from 390 leaves us with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 66

Moving on to step 4:
If we divide 603 by 66, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 594 from 603, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 66

Advancing to step 5:
If we divide 96 by 66, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 591.0
Subtracting 66 from 96 leaves us with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 66

Moving on to step 6:
If we divide 308 by 66, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 5914.0
The remainder is 44 after subtracting 264 from 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
When dividing 440 by 66, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 5914.6
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
When dividing 440 by 66, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5914.66
If we subtract 396 from 440, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 5914.66 with a remainder of 0.044.
