800450 ÷ 43 
We're looking to find how many times 43 goes into 800450.

Let's proceed to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 43

Let's proceed to step 2:
When dividing 80 by 43, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 43 from 80, we get 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 43

Let's proceed to step 3:
When dividing 370 by 43, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 344 away from 370, we end up with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 43

Advancing to step 4:
264 divided by 43 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 186.0
Subtracting 258 from 264 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 43

Going ahead to step 5:
43 can be fit into 65 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 1861.0
The remainder is 22 after subtracting 43 from 65.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 43

Step 6:
When dividing 220 by 43, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 18615.0
If we take 215 away from 220, we end up 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 7:
When dividing 50 by 43, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 18615.1
Deduct 43 from 50 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 43, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 18615.11
Subtract 43 from 70 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 18615.11, and the remainder is 0.027.
