863204 ÷ 43 
We want to divide 863204 by 43.

Going ahead to step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 43

Let's proceed to step 2:
43 can be fit into 86 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 86 away from 86, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 43

Step 3:
If we divide 3 by 43, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 43

On to step 4:
The number 43 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 200.0
If we take 0 away from 32, we end up with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 43

Going ahead to step 5:
43 goes into 320 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 2007.0
If we take 301 away from 320, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 43

Advancing to step 6:
The number 43 fits into 194 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 20074.0
If we subtract 172 from 194, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 43, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 20074.5
Subtracting 215 from 220 leaves us 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 8:
If we divide 50 by 43, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 20074.51
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.

Advancing to step 9:
The number 43 fits into 70 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 20074.511
If we subtract 43 from 70, we 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 20074.511, and the remainder is 0.0027.
