We divide 578386 by 66
We want to divide 578386 by 66.

Advancing to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 66

Step 2:
57 divided by 66 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 66

Going ahead to step 3:
66 goes into 578 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 528 from 578 and we're left with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 66

Let's proceed to step 4:
The number 66 fits into 503 7 times, leaving a remainder of 41.
The next digit of our result is 7. 
Result so far: 87.0
The remainder is 41 after subtracting 462 from 503.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 66

Moving on to step 5:
The number 66 fits into 418 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 876.0
If we subtract 396 from 418, we get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 66

Let's proceed to step 6:
226 divided by 66 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 8763.0
Deduct 198 from 226 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
The number 66 fits into 280 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8763.4
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
66 goes into 160 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 8763.42
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8763.424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 66, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 8763.4242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
280 divided by 66 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8763.42424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8763.424242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
If we divide 280 by 66, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 8763.4242424
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
66 goes into 160 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 8763.42424242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 8763.42424242 with a remainder of 2.8e-08.
