Let's divide 21936499 by 450
We're looking to find how many times 450 goes into 21936499.

Moving on to step 1:
450 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 450

Moving on to step 2:
21 divided by 450 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 450

On to step 3:
When dividing 219 by 450, we get 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Grab the next digit (3) from the dividend, add it to 219, then carry on: 2193 / 450

Let's proceed to step 4:
When dividing 2193 by 450, we get 4 with a remainder of 393.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1800 from 2193 leaves us with 393.
Fetch the next digit (6) from the dividend, attach it to 393 and continue: 3936 / 450

On to step 5:
If we divide 3936 by 450, we get 8 and a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 3600 from 3936, we get 336.
Append the next digit (4) from the dividend to 336 and continue with: 3364 / 450

Moving on to step 6:
The number 450 fits into 3364 7 times, leaving a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 487.0
The remainder is 214 after subtracting 3150 from 3364.
Include the next digit (9) from the dividend after 214, then repeat: 2149 / 450

Going ahead to step 7:
The number 450 fits into 2149 4 times, leaving a remainder of 349.
Record the quotient 4 as the next digit in the result. 
Result so far: 4874.0
If we take 1800 away from 2149, we end up with 349.
Fetch the next digit (9) from the dividend, attach it to 349 and continue: 3499 / 450

Step 8:
The number 450 fits into 3499 7 times, leaving a remainder of 349.
Use 7 as the next digit of our solution. 
Result so far: 48747.0
Deduct 3150 from 3499 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 9:
3490 divided by 450 is 7 with a remainder of 340.
The next digit of our result is 7. 
Result so far: 48747.7
Subtracting 3150 from 3490 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
450 can be fit into 3400 7 times, resulting in a remainder of 250.
Use 7 as the next digit of our solution. 
Result so far: 48747.77
If we take 3150 away from 3400, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Our division results in 48747.77 with a remaining 0.25.
