Let's divide 648660 by 48
We want to figure out the number of times 648660 can be divided by 48.

Going ahead to step 1:
48 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 48

Advancing to step 2:
When dividing 64 by 48, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 48 from 64 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 48

Going ahead to step 3:
48 can be fit into 168 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 144 from 168 leaves us with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 48

Step 4:
246 divided by 48 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 240 from 246 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 48

Advancing to step 5:
The number 48 fits into 66 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1351.0
Subtract 48 from 66 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 48

Going ahead to step 6:
48 goes into 180 3 times with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 13513.0
If we take 144 away from 180, we end up 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.

On to step 7:
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: 13513.7
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 48, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13513.75
If we take 240 away from 240, we end up 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.

Advancing to step 9:
0 divided by 48 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13513.75
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.

Going ahead to step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 13513.75
If we subtract 0 from 0, 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.

The final result is 13513.75 with a remainder of 0.0.
