We're dividing 66528576 by 48 
Let's see how many times 48 fits into 66528576.

Moving on to step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 48

On to step 2:
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: 1.0
Deduct 48 from 66 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 48

Advancing to step 3:
If we divide 185 by 48, we get 3 and a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 144 from 185, we get 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 48

Moving on to step 4:
412 divided by 48 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 138.0
The remainder is 28 after subtracting 384 from 412.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 48

Going ahead to step 5:
48 goes into 288 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1386.0
The remainder is 0 after subtracting 288 from 288.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 48

Advancing to step 6:
48 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 13860.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 48

Advancing to step 7:
48 goes into 57 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 138601.0
If we subtract 48 from 57, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 48

Let's proceed to step 8:
The number 48 fits into 96 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1386012.0
Subtract 96 from 96 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.

Let's proceed to step 9:
If we divide 0 by 48, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1386012.0
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.

Step 10:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1386012.0
The remainder is 0 after subtracting 0 from 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 1386012.0 with a remaining 0.0.
