43799855 ÷ 450 
Let's see how many times 450 fits into 43799855.

Going ahead to step 1:
The number 450 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 450

On to step 2:
If we divide 43 by 450, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 450

Moving on to step 3:
437 divided by 450 is 0 with a remainder of 437.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 437 to get 437.
Include the next digit (9) from the dividend after 437, then repeat: 4379 / 450

Let's proceed to step 4:
The number 450 fits into 4379 9 times, leaving a remainder of 329.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 4050 from 4379, we get 329.
Fetch the next digit (9) from the dividend, attach it to 329 and continue: 3299 / 450

Let's proceed to step 5:
When dividing 3299 by 450, we get 7 with a remainder of 149.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 3150 from 3299 leaves us with 149.
Take the next digit (8) from the dividend and append it to 149, then repeat: 1498 / 450

Let's proceed to step 6:
1498 divided by 450 is 3 with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
Subtracting 1350 from 1498 leaves us with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 450

Step 7:
450 goes into 1485 3 times with a remainder of 135.
The next digit of our result is 3. 
Result so far: 9733.0
If we subtract 1350 from 1485, we get 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 450

Step 8:
The number 450 fits into 1355 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 97333.0
Deduct 1350 from 1355 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 450, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 97333.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 450 is 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 97333.01
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
450 can be fit into 500 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 97333.011
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 97333.011 and a remainder of 0.005.
