331966 divided by 78 
Let's see how many times 78 fits into 331966.

Moving on to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 78

Let's proceed to step 2:
When dividing 33 by 78, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 78

Let's proceed to step 3:
The number 78 fits into 331 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 312 from 331 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 78

Going ahead to step 4:
The number 78 fits into 199 2 times, leaving a remainder of 43.
The next digit of our result is 2. 
Result so far: 42.0
If we take 156 away from 199, we end up with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 78

Moving on to step 5:
If we divide 436 by 78, we get 5 and a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 425.0
If we take 390 away from 436, we end up with 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 78

Going ahead to step 6:
If we divide 466 by 78, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 4255.0
Deduct 390 from 466 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 7:
If we divide 760 by 78, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 4255.9
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 4255.97
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 78, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4255.974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 4255.9743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4255.97435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
78 goes into 700 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 4255.974358
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 4255.9743589
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4255.97435897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 4255.97435897 with a remaining 3.4e-08.
