We look at the division of 30129592 by 663 
We want to divide 30129592 by 663.

Advancing to step 1:
The number 663 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 663

Moving on to step 2:
30 divided by 663 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 663

Step 3:
301 divided by 663 is 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Fetch the next digit (2) from the dividend, attach it to 301 and continue: 3012 / 663

Let's proceed to step 4:
663 can be fit into 3012 4 times, resulting in a remainder of 360.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2652 from 3012 to get 360.
Bring next digit (9) of the dividend behind the 360 and repeat the process: 3609 / 663

Going ahead to step 5:
663 goes into 3609 5 times with a remainder of 294.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 294 after subtracting 3315 from 3609.
Take the next digit (5) from the dividend and append it to 294, then repeat: 2945 / 663

On to step 6:
If we divide 2945 by 663, we get 4 and a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 454.0
The remainder is 293 after subtracting 2652 from 2945.
Take the next digit (9) from the dividend and append it to 293, then repeat: 2939 / 663

On to step 7:
663 can be fit into 2939 4 times, resulting in a remainder of 287.
The number 4 becomes the next digit in our result. 
Result so far: 4544.0
Deduct 2652 from 2939 and we're left with 287.
Fetch the next digit (2) from the dividend, attach it to 287 and continue: 2872 / 663

Step 8:
663 can be fit into 2872 4 times, resulting in a remainder of 220.
The next digit of our result is 4. 
Result so far: 45444.0
Subtracting 2652 from 2872 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 9:
663 can be fit into 2200 3 times, resulting in a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 45444.3
If we take 1989 away from 2200, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 10:
When dividing 2110 by 663, we get 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 45444.33
Subtract 1989 from 2110 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The quotient of the division is 45444.33, and the remainder is 0.121.
