We divide 636876 by 99
We want to divide 636876 by 99.

Moving on to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 99

On to step 2:
63 divided by 99 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 99

Moving on to step 3:
When dividing 636 by 99, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 594 from 636 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 99

Step 4:
428 divided by 99 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 396 from 428 and we're left with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 99

Going ahead to step 5:
327 divided by 99 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 643.0
Deduct 297 from 327 and we're left with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 99

Moving on to step 6:
The number 99 fits into 306 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 6433.0
Subtract 297 from 306 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 99 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 6433.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 8:
99 goes into 900 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 6433.09
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
If we divide 90 by 99, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 6433.09
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
99 goes into 900 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6433.0909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
99 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 6433.0909
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
900 divided by 99 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 6433.090909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
The number 99 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 6433.090909
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
When dividing 900 by 99, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 6433.09090909
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 6433.09090909 with a remainder of 9e-09.
