Let's divide 340257 by 81
Our goal is to divide 340257 by 81.

Moving on to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 81

Advancing to step 2:
34 divided by 81 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 81

Going ahead to step 3:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 324 from 340 leaves us with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 81

Going ahead to step 4:
162 divided by 81 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 162 from 162, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 81

Going ahead to step 5:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 420.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 81

Going ahead to step 6:
The number 81 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 4200.0
If we subtract 0 from 57, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
81 goes into 570 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4200.7
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4200.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 81, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 4200.703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
81 goes into 570 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4200.7037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
81 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4200.7037
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 81 fits into 300 3 times, leaving a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 4200.703703
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
If we divide 570 by 81, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4200.7037037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
If we divide 30 by 81, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4200.7037037
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 4200.7037037 with a remainder of 3e-08.
