We divide 639072 by 99
Let's see how many times 99 fits into 639072.

Advancing to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 99

On to step 2:
The number 99 fits into 63 0 times, leaving a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 99

On to step 3:
99 goes into 639 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 594 from 639, we get 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 99

Let's proceed to step 4:
If we divide 450 by 99, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 396 from 450 and we're left with 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 99

Step 5:
If we divide 547 by 99, we get 5 and a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 645.0
The remainder is 52 after subtracting 495 from 547.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 99

Step 6:
When dividing 522 by 99, we get 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 6455.0
Deduct 495 from 522 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 99 is 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 6455.2
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
720 divided by 99 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 6455.27
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
99 can be fit into 270 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 6455.272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
If we divide 720 by 99, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 6455.2727
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
If we divide 270 by 99, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 6455.27272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
99 goes into 720 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 6455.272727
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
If we divide 270 by 99, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 6455.2727272
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
The number 99 fits into 720 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 6455.27272727
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 6455.27272727 and a remainder of 2.7e-08.
