We divide 603996 by 78
Let's see how many times 78 fits into 603996.

Step 1:
6 divided by 78 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 78

Going ahead to step 2:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 78

Moving on to step 3:
If we divide 603 by 78, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 57 after subtracting 546 from 603.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 78

On to step 4:
When dividing 579 by 78, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 546 from 579, we get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 78

Going ahead to step 5:
339 divided by 78 is 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 774.0
Subtracting 312 from 339 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 78

Step 6:
78 can be fit into 276 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 7743.0
Subtracting 234 from 276 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7743.5
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 78, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 7743.53
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
78 can be fit into 660 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 7743.538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 78 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 7743.5384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 78, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 7743.53846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 7743.538461
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
420 divided by 78 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7743.5384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 7743.53846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 7743.53846153 with a remaining 6.6e-08.
