336239 divided by 81 
Let's see how many times 81 fits into 336239.

On to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 81

Going ahead to step 2:
81 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 81

Going ahead to step 3:
336 divided by 81 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 324 from 336 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 81

Advancing to step 4:
81 can be fit into 122 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 41 after subtracting 81 from 122.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 81

Advancing to step 5:
The number 81 fits into 413 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
If we subtract 405 from 413, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 81

Advancing to step 6:
89 divided by 81 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 4151.0
If we subtract 81 from 89, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4151.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
When dividing 800 by 81, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 4151.09
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 4151.098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
81 goes into 620 7 times with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 4151.0987
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4151.09876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
81 goes into 440 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4151.098765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
If we divide 350 by 81, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 4151.0987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
When dividing 260 by 81, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4151.09876543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 4151.09876543 with a remaining 1.7e-08.
