When dividing 3 by 843, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 843

On to step 2:
843 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 843

Advancing to step 3:
When dividing 317 by 843, we get 0 with a remainder of 317.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 317 leaves us with 317.
Grab the next digit (7) from the dividend, add it to 317, then carry on: 3177 / 843

Let's proceed to step 4:
3177 divided by 843 is 3 with a remainder of 648.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2529 from 3177 and we're left with 648.
Grab the next digit (3) from the dividend, add it to 648, then carry on: 6483 / 843

On to step 5:
If we divide 6483 by 843, we get 7 and a remainder of 582.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 5901 from 6483 to get 582.
Include the next digit (3) from the dividend after 582, then repeat: 5823 / 843

Going ahead to step 6:
If we divide 5823 by 843, we get 6 and a remainder of 765.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we take 5058 away from 5823, we end up with 765.
Include the next digit (0) from the dividend after 765, then repeat: 7650 / 843

Going ahead to step 7:
7650 divided by 843 is 9 with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 3769.0
Deduct 7587 from 7650 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 843

Moving on to step 8:
634 divided by 843 is 0 with a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 37690.0
The remainder is 634 after subtracting 0 from 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 9:
If we divide 6340 by 843, we get 7 and a remainder of 439.
Record the quotient 7 as the next digit in the result. 
Result so far: 37690.7
The remainder is 439 after subtracting 5901 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 10:
When dividing 4390 by 843, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 37690.75
If we take 4215 away from 4390, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
When dividing 1750 by 843, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 37690.752
Subtracting 1686 from 1750 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
843 can be fit into 640 0 times, resulting in a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 37690.752
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
When dividing 6400 by 843, we get 7 with a remainder of 499.
Use 7 as the next digit of our solution. 
Result so far: 37690.75207
If we take 5901 away from 6400, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Let's proceed to step 14:
4990 divided by 843 is 5 with a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 37690.752075
Subtracting 4215 from 4990 leaves us with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 15:
When dividing 7750 by 843, we get 9 with a remainder of 163.
Write down 9 as next digit of the result. 
Result so far: 37690.7520759
Subtract 7587 from 7750 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 16:
If we divide 1630 by 843, we get 1 and a remainder of 787.
Record the quotient 1 as the next digit in the result. 
Result so far: 37690.75207591
If we take 843 away from 1630, we end up with 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

The final result is 37690.75207591 with a remainder of 7.87e-07.
