Let's divide 396933 by 78
Let's see how many times 78 fits into 396933.

Going ahead to step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 78

Moving on to step 2:
If we divide 39 by 78, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 78

Step 3:
If we divide 396 by 78, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 390 from 396, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 78

Moving on to step 4:
78 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 69 leaves us with 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 78

Advancing to step 5:
The number 78 fits into 693 8 times, leaving a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
The remainder is 69 after subtracting 624 from 693.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 78

Advancing to step 6:
78 can be fit into 693 8 times, resulting in a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 5088.0
The remainder is 69 after subtracting 624 from 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
When dividing 690 by 78, we get 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 5088.8
The remainder is 66 after subtracting 624 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 5088.88
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 5088.88 and a remainder of 0.036.
