We're dividing 621036 by 99 
We're looking to find how many times 99 goes into 621036.

On to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 99

Step 2:
62 divided by 99 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 99

Step 3:
When dividing 621 by 99, we get 6 with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 594 from 621 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 99

Going ahead to step 4:
270 divided by 99 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 198 away from 270, we end up with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 99

Let's proceed to step 5:
99 can be fit into 723 7 times, resulting in a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 627.0
Deduct 693 from 723 and we're left with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 99

Moving on to step 6:
99 goes into 306 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 6273.0
The remainder is 9 after subtracting 297 from 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 99 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 6273.0
The remainder is 90 after subtracting 0 from 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:
When dividing 900 by 99, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 6273.09
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.

Advancing to step 9:
When dividing 90 by 99, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 6273.09
If we subtract 0 from 90, we 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.

Moving on to step 10:
If we divide 900 by 99, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 6273.0909
Subtracting 891 from 900 leaves us 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.

On 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: 6273.0909
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.

Going ahead to step 12:
The number 99 fits into 900 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 6273.090909
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.

Going ahead to step 13:
99 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 6273.090909
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 14:
If we divide 900 by 99, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 6273.09090909
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.

After the division, we end up with 6273.09090909 and a remainder of 9e-09.
