Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 843

Moving on to step 2:
843 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 843

On to step 3:
If we divide 194 by 843, we get 0 and a remainder of 194.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 194 to get 194.

On to step 4:
843 goes into 1948 2 times with a remainder of 262.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1686 from 1948 leaves us with 262.
Take the next digit (4) from the dividend and append it to 262, then repeat: 2624 / 843

Moving on to step 5:
The number 843 fits into 2624 3 times, leaving a remainder of 95.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 95 after subtracting 2529 from 2624.
Include the next digit (4) from the dividend after 95, then repeat: 954 / 843

Going ahead to step 6:
When dividing 954 by 843, we get 1 with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 231.0
Deduct 843 from 954 and we're left with 111.
Grab the next digit (5) from the dividend, add it to 111, then carry on: 1115 / 843

Advancing to step 7:
The number 843 fits into 1115 1 times, leaving a remainder of 272.
Write down 1 as next digit of the result. 
Result so far: 2311.0
Subtract 843 from 1115 to get 272.
Take the next digit (6) from the dividend and append it to 272, then repeat: 2726 / 843

Moving on to step 8:
843 can be fit into 2726 3 times, resulting in a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 23113.0
The remainder is 197 after subtracting 2529 from 2726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
The number 843 fits into 1970 2 times, leaving a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 23113.2
Subtract 1686 from 1970 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 10:
843 goes into 2840 3 times with a remainder of 311.
The next digit of our result is 3. 
Result so far: 23113.23
The remainder is 311 after subtracting 2529 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 11:
843 can be fit into 3110 3 times, resulting in a remainder of 581.
The next digit of our result is 3. 
Result so far: 23113.233
Subtract 2529 from 3110 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Our division results in 23113.233 with a remaining 0.0581.
