Let's divide 171823 by 43
We want to figure out the number of times 171823 can be divided by 43.

Advancing to step 1:
1 divided by 43 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 43

Moving on to step 2:
When dividing 17 by 43, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 43

On to step 3:
171 divided by 43 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 129 from 171 and we're left with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 43

Let's proceed to step 4:
428 divided by 43 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 39.0
If we take 387 away from 428, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 43

Step 5:
The number 43 fits into 412 9 times, leaving a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
If we take 387 away from 412, we end up with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 43

Moving on to step 6:
The number 43 fits into 253 5 times, leaving a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 3995.0
Subtracting 215 from 253 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3995.8
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3995.88
If we subtract 344 from 360, we 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 3995.88, and the remainder is 0.016.
