66458312 divided by 663 
We want to figure out the number of times 66458312 can be divided by 663.

On to step 1:
The number 663 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 663

Step 2:
663 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 663

On to step 3:
When dividing 664 by 663, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 663 from 664 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 663

On to step 4:
When dividing 15 by 663, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 15, we get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 663

Step 5:
663 can be fit into 158 0 times, resulting in a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 158 and we're left with 158.
Fetch the next digit (3) from the dividend, attach it to 158 and continue: 1583 / 663

Moving on to step 6:
If we divide 1583 by 663, we get 2 and a remainder of 257.
The next digit of our result is 2. 
Result so far: 1002.0
Deduct 1326 from 1583 and we're left with 257.
Take the next digit (1) from the dividend and append it to 257, then repeat: 2571 / 663

Let's proceed to step 7:
If we divide 2571 by 663, we get 3 and a remainder of 582.
Put 3 as the next digit of the answer. 
Result so far: 10023.0
Deduct 1989 from 2571 and we're left with 582.
Fetch the next digit (2) from the dividend, attach it to 582 and continue: 5822 / 663

Step 8:
When dividing 5822 by 663, we get 8 with a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 100238.0
If we take 5304 away from 5822, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 9:
663 can be fit into 5180 7 times, resulting in a remainder of 539.
Write down 7 as next digit of the result. 
Result so far: 100238.7
Deduct 4641 from 5180 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 10:
The number 663 fits into 5390 8 times, leaving a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 100238.78
Subtract 5304 from 5390 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
860 divided by 663 is 1 with a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 100238.781
If we take 663 away from 860, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 12:
If we divide 1970 by 663, we get 2 and a remainder of 644.
Record the quotient 2 as the next digit in the result. 
Result so far: 100238.7812
If we subtract 1326 from 1970, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 13:
If we divide 6440 by 663, we get 9 and a remainder of 473.
Record the quotient 9 as the next digit in the result. 
Result so far: 100238.78129
If we take 5967 away from 6440, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 14:
663 can be fit into 4730 7 times, resulting in a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 100238.781297
If we take 4641 away from 4730, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 15:
890 divided by 663 is 1 with a remainder of 227.
Use 1 as the next digit of our solution. 
Result so far: 100238.7812971
Subtracting 663 from 890 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 16:
When dividing 2270 by 663, we get 3 with a remainder of 281.
Use 3 as the next digit of our solution. 
Result so far: 100238.78129713
Subtract 1989 from 2270 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

After the division, we end up with 100238.78129713 and a remainder of 2.81e-07.
