We're dividing 78287439 by 334 
We want to divide 78287439 by 334.

Going ahead to step 1:
7 divided by 334 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 334

Advancing to step 2:
When dividing 78 by 334, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 334

Step 3:
334 can be fit into 782 2 times, resulting in a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 668 from 782 and we're left with 114.
Fetch the next digit (8) from the dividend, attach it to 114 and continue: 1148 / 334

Let's proceed to step 4:
1148 divided by 334 is 3 with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 1002 from 1148 and we're left with 146.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 334

Moving on to step 5:
1467 divided by 334 is 4 with a remainder of 131.
Use 4 as the next digit of our solution. 
Result so far: 234.0
Subtracting 1336 from 1467 leaves us with 131.
Include the next digit (4) from the dividend after 131, then repeat: 1314 / 334

Advancing to step 6:
334 goes into 1314 3 times with a remainder of 312.
Write down 3 as next digit of the result. 
Result so far: 2343.0
The remainder is 312 after subtracting 1002 from 1314.
Bring next digit (3) of the dividend behind the 312 and repeat the process: 3123 / 334

Step 7:
334 goes into 3123 9 times with a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 23439.0
Subtracting 3006 from 3123 leaves us with 117.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 334

Going ahead to step 8:
334 goes into 1179 3 times with a remainder of 177.
Put 3 as the next digit of the answer. 
Result so far: 234393.0
Subtract 1002 from 1179 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 9:
1770 divided by 334 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 234393.5
Deduct 1670 from 1770 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
The number 334 fits into 1000 2 times, leaving a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 234393.52
If we take 668 away from 1000, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
334 can be fit into 3320 9 times, resulting in a remainder of 314.
Record the quotient 9 as the next digit in the result. 
Result so far: 234393.529
Deduct 3006 from 3320 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 12:
When dividing 3140 by 334, we get 9 with a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 234393.5299
The remainder is 134 after subtracting 3006 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 234393.5299 and a remainder of 0.00134.
