315040 ÷ 66 
We're looking to find how many times 66 goes into 315040.

Let's proceed to step 1:
66 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 66

On to step 2:
The number 66 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 66

Going ahead to step 3:
66 goes into 315 4 times with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 264 from 315 leaves us with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 66

Step 4:
66 can be fit into 510 7 times, resulting in a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 462 from 510 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 66

Moving on to step 5:
66 goes into 484 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we take 462 away from 484, we end up with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 66

Let's proceed to step 6:
220 divided by 66 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 4773.0
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
66 goes into 220 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4773.3
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
66 goes into 220 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4773.33
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 4773.33 with a remaining 0.022.
