664820 divided by 48 
We're looking to find how many times 48 goes into 664820.

Step 1:
6 divided by 48 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 48

Moving on to step 2:
48 goes into 66 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 48 from 66, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 48

On to step 3:
48 goes into 184 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 40 after subtracting 144 from 184.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 48

Going ahead to step 4:
48 can be fit into 408 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we subtract 384 from 408, we get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 48

On to step 5:
242 divided by 48 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1385.0
If we take 240 away from 242, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 48

Step 6:
The number 48 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13850.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 48 fits into 200 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13850.4
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
When dividing 80 by 48, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 13850.41
Deduct 48 from 80 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 13850.416
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 13850.4166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 13850.4166 and a remainder of 0.00032.
