We're dividing 235355 by 78 
We want to divide 235355 by 78.

Step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 78

Step 2:
23 divided by 78 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 78

Step 3:
78 goes into 235 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 234 from 235 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 78

Moving on to step 4:
The number 78 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 78

Going ahead to step 5:
78 goes into 135 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
If we take 78 away from 135, we end up with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 78

Moving on to step 6:
If we divide 575 by 78, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 3017.0
If we subtract 546 from 575, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
If we divide 290 by 78, we get 3 and a remainder of 56.
The next digit of our result is 3. 
Result so far: 3017.3
Subtracting 234 from 290 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
If we divide 560 by 78, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 3017.37
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
If we divide 140 by 78, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 3017.371
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
78 goes into 620 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 3017.3717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
If we divide 740 by 78, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 3017.37179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 3017.371794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 3017.3717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
560 divided by 78 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 3017.37179487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 3017.37179487 with a remainder of 1.4e-08.
