Let's divide 23883245 by 621
We want to divide 23883245 by 621.

On to step 1:
The number 621 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 621

Let's proceed to step 2:
If we divide 23 by 621, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 621

On to step 3:
621 can be fit into 238 0 times, resulting in a remainder of 238.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 238, we get 238.
Bring next digit (8) of the dividend behind the 238 and repeat the process: 2388 / 621

Step 4:
621 goes into 2388 3 times with a remainder of 525.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1863 from 2388 and we're left with 525.
Grab the next digit (3) from the dividend, add it to 525, then carry on: 5253 / 621

On to step 5:
621 can be fit into 5253 8 times, resulting in a remainder of 285.
The next digit of our result is 8. 
Result so far: 38.0
If we take 4968 away from 5253, we end up with 285.
Fetch the next digit (2) from the dividend, attach it to 285 and continue: 2852 / 621

On to step 6:
If we divide 2852 by 621, we get 4 and a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 384.0
The remainder is 368 after subtracting 2484 from 2852.
Append the next digit (4) from the dividend to 368 and continue with: 3684 / 621

Step 7:
When dividing 3684 by 621, we get 5 with a remainder of 579.
Put 5 as the next digit of the answer. 
Result so far: 3845.0
Subtracting 3105 from 3684 leaves us with 579.
Take the next digit (5) from the dividend and append it to 579, then repeat: 5795 / 621

Step 8:
621 can be fit into 5795 9 times, resulting in a remainder of 206.
Write down 9 as next digit of the result. 
Result so far: 38459.0
Subtracting 5589 from 5795 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
If we divide 2060 by 621, we get 3 and a remainder of 197.
The next digit of our result is 3. 
Result so far: 38459.3
Subtracting 1863 from 2060 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 10:
1970 divided by 621 is 3 with a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 38459.33
If we subtract 1863 from 1970, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 38459.33 with a remainder of 0.107.
