If we divide 8 by 339, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 339

On to step 2:
81 divided by 339 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 339

Moving on to step 3:
If we divide 819 by 339, we get 2 and a remainder of 141.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 141 after subtracting 678 from 819.
Fetch the next digit (3) from the dividend, attach it to 141 and continue: 1413 / 339

Moving on to step 4:
339 can be fit into 1413 4 times, resulting in a remainder of 57.
The next digit of our result is 4. 
Result so far: 24.0
Deduct 1356 from 1413 and we're left with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 339

Let's proceed to step 5:
If we divide 571 by 339, we get 1 and a remainder of 232.
Put 1 as the next digit of the answer. 
Result so far: 241.0
Subtracting 339 from 571 leaves us with 232.
Grab the next digit (5) from the dividend, add it to 232, then carry on: 2325 / 339

Let's proceed to step 6:
When dividing 2325 by 339, we get 6 with a remainder of 291.
Write down 6 as next digit of the result. 
Result so far: 2416.0
Subtracting 2034 from 2325 leaves us with 291.
Take the next digit (0) from the dividend and append it to 291, then repeat: 2910 / 339

Step 7:
If we divide 2910 by 339, we get 8 and a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 24168.0
The remainder is 198 after subtracting 2712 from 2910.
Grab the next digit (8) from the dividend, add it to 198, then carry on: 1988 / 339

On to step 8:
339 can be fit into 1988 5 times, resulting in a remainder of 293.
Use 5 as the next digit of our solution. 
Result so far: 241685.0
The remainder is 293 after subtracting 1695 from 1988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
2930 divided by 339 is 8 with a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 241685.8
Subtract 2712 from 2930 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
If we divide 2180 by 339, we get 6 and a remainder of 146.
Record the quotient 6 as the next digit in the result. 
Result so far: 241685.86
Subtracting 2034 from 2180 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
The number 339 fits into 1460 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 241685.864
If we take 1356 away from 1460, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
339 goes into 1040 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 241685.8643
Subtract 1017 from 1040 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
230 divided by 339 is 0 with a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 241685.8643
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 14:
339 can be fit into 2300 6 times, resulting in a remainder of 266.
Put 6 as the next digit of the answer. 
Result so far: 241685.864306
If we take 2034 away from 2300, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 15:
If we divide 2660 by 339, we get 7 and a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 241685.8643067
The remainder is 287 after subtracting 2373 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 16:
When dividing 2870 by 339, we get 8 with a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 241685.86430678
The remainder is 158 after subtracting 2712 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The quotient of the division is 241685.86430678, and the remainder is 1.58e-07.
