409551 ÷ 43 
Our goal is to divide 409551 by 43.

On to step 1:
4 divided by 43 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 43

Let's proceed to step 2:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 43

Advancing to step 3:
409 divided by 43 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 387 from 409 leaves us with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 43

Moving on to step 4:
225 divided by 43 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 95.0
The remainder is 10 after subtracting 215 from 225.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 43

Moving on to step 5:
105 divided by 43 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 952.0
If we take 86 away from 105, we end up with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 43

Advancing to step 6:
191 divided by 43 is 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 9524.0
The remainder is 19 after subtracting 172 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 43 fits into 190 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9524.4
If we take 172 away from 190, we end up with 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: 9524.44
Deduct 172 from 180 and we're left with 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 9524.44, and the remainder is 0.008.
