393370 ÷ 66 
We're looking to find how many times 66 goes into 393370.

Moving on to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
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

On to step 2:
39 divided by 66 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 66

Let's proceed to step 3:
If we divide 393 by 66, we get 5 and a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 63 after subtracting 330 from 393.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 66

On to step 4:
If we divide 633 by 66, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtracting 594 from 633 leaves us with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 66

Moving on to step 5:
66 can be fit into 397 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 596.0
Subtract 396 from 397 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 66

Going ahead to step 6:
10 divided by 66 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5960.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 5960.1
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5960.15
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
66 goes into 100 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 5960.151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
66 can be fit into 340 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5960.1515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
66 can be fit into 100 1 times, resulting in a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 5960.15151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
66 can be fit into 340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5960.151515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 66 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 5960.1515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
If we divide 340 by 66, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5960.15151515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 5960.15151515 with a balance of 1e-08.
