319807 divided by 78 
Let's see how many times 78 fits into 319807.

Going ahead to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 78

Step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 78

Advancing to step 3:
78 goes into 319 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 312 from 319 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 78

Advancing to step 4:
78 goes into 78 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtracting 78 from 78 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 78

Advancing to step 5:
If we divide 0 by 78, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 410.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 78

Let's proceed to step 6:
78 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 4100.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
78 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4100.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 78, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 4100.08
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 9:
760 divided by 78 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 4100.089
If we take 702 away from 760, we end up 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.

Step 10:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 4100.0897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 4100.08974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
When dividing 280 by 78, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 4100.089743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
460 divided by 78 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 4100.0897435
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.

Going ahead to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 4100.08974358
Subtract 624 from 700 to 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.

Our division results in 4100.08974358 with a remaining 7.6e-08.
