We look at the division of 49645648 by 663 
Let's see how many times 663 fits into 49645648.

On to step 1:
663 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 663

Step 2:
If we divide 49 by 663, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 663

Let's proceed to step 3:
When dividing 496 by 663, we get 0 with a remainder of 496.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 496 after subtracting 0 from 496.
Take the next digit (4) from the dividend and append it to 496, then repeat: 4964 / 663

Going ahead to step 4:
4964 divided by 663 is 7 with a remainder of 323.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 4641 away from 4964, we end up with 323.
Take the next digit (5) from the dividend and append it to 323, then repeat: 3235 / 663

Let's proceed to step 5:
663 goes into 3235 4 times with a remainder of 583.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 2652 from 3235 to get 583.
Fetch the next digit (6) from the dividend, attach it to 583 and continue: 5836 / 663

Let's proceed to step 6:
5836 divided by 663 is 8 with a remainder of 532.
Put 8 as the next digit of the answer. 
Result so far: 748.0
Deduct 5304 from 5836 and we're left with 532.
Fetch the next digit (4) from the dividend, attach it to 532 and continue: 5324 / 663

Let's proceed to step 7:
663 goes into 5324 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 7488.0
If we take 5304 away from 5324, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 663

Advancing to step 8:
663 goes into 208 0 times with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 74880.0
Subtract 0 from 208 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 9:
663 goes into 2080 3 times with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 74880.3
Subtract 1989 from 2080 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 10:
910 divided by 663 is 1 with a remainder of 247.
The number 1 becomes the next digit in our result. 
Result so far: 74880.31
Subtract 663 from 910 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 11:
663 can be fit into 2470 3 times, resulting in a remainder of 481.
Use 3 as the next digit of our solution. 
Result so far: 74880.313
Subtract 1989 from 2470 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 12:
The number 663 fits into 4810 7 times, leaving a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 74880.3137
Subtract 4641 from 4810 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 13:
663 can be fit into 1690 2 times, resulting in a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 74880.31372
Subtract 1326 from 1690 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 14:
663 goes into 3640 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 74880.313725
Subtracting 3315 from 3640 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 15:
663 can be fit into 3250 4 times, resulting in a remainder of 598.
The next digit of our result is 4. 
Result so far: 74880.3137254
Deduct 2652 from 3250 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 16:
5980 divided by 663 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 74880.31372549
If we subtract 5967 from 5980, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 74880.31372549 with a remaining 1.3e-08.
