Let's divide 393345 by 78
Our goal is to divide 393345 by 78.

Going ahead to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 78

Let's proceed to step 2:
78 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 78

Let's proceed to step 3:
78 goes into 393 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 390 away from 393, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 78

Step 4:
33 divided by 78 is 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 78

Let's proceed to step 5:
If we divide 334 by 78, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 504.0
Subtract 312 from 334 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 78

Advancing to step 6:
78 can be fit into 225 2 times, resulting in a remainder of 69.
The next digit of our result is 2. 
Result so far: 5042.0
If we take 156 away from 225, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
78 goes into 690 8 times with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 5042.8
Subtracting 624 from 690 leaves us 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.

Moving on to step 8:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 5042.88
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 5042.88 with a remaining 0.036.
