581809 ÷ 43 
Let's see how many times 43 fits into 581809.

Advancing to step 1:
If we divide 5 by 43, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 43

Step 2:
43 can be fit into 58 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 58, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 43

Going ahead to step 3:
151 divided by 43 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 129 from 151, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 43

Step 4:
When dividing 228 by 43, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
If we subtract 215 from 228, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 43

Step 5:
43 can be fit into 130 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1353.0
Subtracting 129 from 130 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 43

Let's proceed to step 6:
If we divide 19 by 43, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 13530.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 13530.4
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 43 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 13530.44
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 13530.44, and the remainder is 0.008.
