We're dividing 450999 by 43 
Our goal is to divide 450999 by 43.

Step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 43

Advancing to step 2:
The number 43 fits into 45 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 43 from 45 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 43

Going ahead to step 3:
43 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 43

On to step 4:
If we divide 209 by 43, we get 4 and a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtracting 172 from 209 leaves us with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 43

Let's proceed to step 5:
The number 43 fits into 379 8 times, leaving a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 1048.0
If we subtract 344 from 379, we get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 43

On to step 6:
43 goes into 359 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 10488.0
Subtract 344 from 359 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 10488.3
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
43 goes into 210 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 10488.34
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
When dividing 380 by 43, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 10488.348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 10488.3488
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 10488.3488, and the remainder is 0.00016.
