340384 ÷ 81 
Our goal is to divide 340384 by 81.

On to step 1:
3 divided by 81 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 81

Advancing to step 2:
When dividing 34 by 81, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 81

Let's proceed to step 3:
340 divided by 81 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 324 from 340 to get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 81

Moving on to step 4:
When dividing 163 by 81, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 162 from 163 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 81

Step 5:
81 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we subtract 0 from 18, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 81

Step 6:
If we divide 184 by 81, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 4202.0
If we take 162 away from 184, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 4202.2
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
When dividing 580 by 81, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 4202.27
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4202.271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
490 divided by 81 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4202.2716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4202.2716
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 81, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4202.271604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
81 goes into 760 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 4202.2716049
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 4202.27160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 4202.27160493 with a remainder of 6.7e-08.
