We look at the division of 663574 by 99 
We want to figure out the number of times 663574 can be divided by 99.

On to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 99

Moving on to step 2:
99 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 99

Moving on to step 3:
99 can be fit into 663 6 times, resulting in a remainder of 69.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 594 from 663 to get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 99

Going ahead to step 4:
When dividing 695 by 99, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we take 693 away from 695, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 99

On to step 5:
When dividing 27 by 99, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 670.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 99

Let's proceed to step 6:
The number 99 fits into 274 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 6702.0
Subtracting 198 from 274 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
If we divide 760 by 99, we get 7 and a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 6702.7
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 8:
99 can be fit into 670 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 6702.76
Subtracting 594 from 670 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
760 divided by 99 is 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 6702.767
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 10:
670 divided by 99 is 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 6702.7676
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 99 is 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 6702.76767
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
If we divide 670 by 99, we get 6 and a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 6702.767676
Subtract 594 from 670 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
760 divided by 99 is 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 6702.7676767
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 14:
99 can be fit into 670 6 times, resulting in a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 6702.76767676
Subtracting 594 from 670 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 6702.76767676 and a remainder of 7.6e-08.
