36621 ÷ 99 
We want to divide 36621 by 99.

On to step 1:
3 divided by 99 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 99

Advancing to step 2:
The number 99 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 99

Going ahead to step 3:
If we divide 366 by 99, we get 3 and a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 297 from 366, we get 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 99

Moving on to step 4:
If we divide 692 by 99, we get 6 and a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 594 away from 692, we end up with 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 99

Going ahead to step 5:
981 divided by 99 is 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 369.0
Subtracting 891 from 981 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.

On to step 6:
The number 99 fits into 900 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 369.9
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 7:
99 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 369.9
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.

Step 8:
The number 99 fits into 900 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 369.909
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.

Moving on to step 9:
If we divide 90 by 99, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 369.909
Deduct 0 from 90 and we're left 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 10:
When dividing 900 by 99, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 369.90909
If we take 891 away from 900, we end up 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.

Advancing to step 11:
If we divide 90 by 99, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 369.90909
Subtract 0 from 90 to get 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 12:
99 can be fit into 900 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 369.9090909
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.

Let's proceed to step 13:
99 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 369.9090909
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 369.9090909 with a remainder of 9e-08.
