We look at the division of 4656660 by 663 
Let's see how many times 663 fits into 4656660.

Advancing to step 1:
4 divided by 663 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 663

Let's proceed to step 2:
If we divide 46 by 663, we get 0 and a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 663

Going ahead to step 3:
If we divide 465 by 663, we get 0 and a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 465 and we're left with 465.
Fetch the next digit (6) from the dividend, attach it to 465 and continue: 4656 / 663

Step 4:
4656 divided by 663 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 4641 from 4656 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 663

Moving on to step 5:
156 divided by 663 is 0 with a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 156 after subtracting 0 from 156.
Include the next digit (6) from the dividend after 156, then repeat: 1566 / 663

Going ahead to step 6:
663 can be fit into 1566 2 times, resulting in a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 702.0
Deduct 1326 from 1566 and we're left with 240.
Bring next digit (0) of the dividend behind the 240 and repeat the process: 2400 / 663

On to step 7:
If we divide 2400 by 663, we get 3 and a remainder of 411.
The number 3 becomes the next digit in our result. 
Result so far: 7023.0
If we subtract 1989 from 2400, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 8:
663 goes into 4110 6 times with a remainder of 132.
The next digit of our result is 6. 
Result so far: 7023.6
The remainder is 132 after subtracting 3978 from 4110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 9:
663 goes into 1320 1 times with a remainder of 657.
Put 1 as the next digit of the answer. 
Result so far: 7023.61
Subtract 663 from 1320 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 10:
The number 663 fits into 6570 9 times, leaving a remainder of 603.
Record the quotient 9 as the next digit in the result. 
Result so far: 7023.619
Deduct 5967 from 6570 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 11:
The number 663 fits into 6030 9 times, leaving a remainder of 63.
The next digit of our result is 9. 
Result so far: 7023.6199
The remainder is 63 after subtracting 5967 from 6030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 7023.6199 with a remainder of 0.00063.
