78359137 ÷ 338 
We want to divide 78359137 by 338.

On to step 1:
If we divide 7 by 338, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 338

Going ahead to step 2:
If we divide 78 by 338, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 338

On to step 3:
338 goes into 783 2 times with a remainder of 107.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 676 from 783 leaves us with 107.
Include the next digit (5) from the dividend after 107, then repeat: 1075 / 338

Let's proceed to step 4:
The number 338 fits into 1075 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 1014 from 1075 and we're left with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 338

Advancing to step 5:
338 can be fit into 619 1 times, resulting in a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 231.0
Subtract 338 from 619 to get 281.
Bring next digit (1) of the dividend behind the 281 and repeat the process: 2811 / 338

On to step 6:
338 goes into 2811 8 times with a remainder of 107.
The number 8 becomes the next digit in our result. 
Result so far: 2318.0
Subtract 2704 from 2811 to get 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 338

Advancing to step 7:
1073 divided by 338 is 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 23183.0
Subtracting 1014 from 1073 leaves us with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 338

Advancing to step 8:
597 divided by 338 is 1 with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 231831.0
If we subtract 338 from 597, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
When dividing 2590 by 338, we get 7 with a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 231831.7
Deduct 2366 from 2590 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 10:
2240 divided by 338 is 6 with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 231831.76
Subtract 2028 from 2240 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
The number 338 fits into 2120 6 times, leaving a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 231831.766
If we subtract 2028 from 2120, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 231831.766 with a remainder of 0.0092.
