664866 divided by 48 
We're looking to find how many times 48 goes into 664866.

Let's proceed to step 1:
48 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 48

Step 2:
The number 48 fits into 66 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 48 away from 66, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 48

On to step 3:
48 goes into 184 3 times with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 144 from 184, we get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 48

Step 4:
When dividing 408 by 48, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Deduct 384 from 408 and we're left with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 48

Let's proceed to step 5:
The number 48 fits into 246 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
The remainder is 6 after subtracting 240 from 246.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 48

On to step 6:
48 can be fit into 66 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 13851.0
If we take 48 away from 66, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 48 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 13851.3
Subtracting 144 from 180 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.

Going ahead to step 8:
If we divide 360 by 48, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 13851.37
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
48 goes into 240 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 13851.375
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
When dividing 0 by 48, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13851.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13851.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13851.375 with a remaining 0.0.
