We're dividing 239979 by 78 
We want to divide 239979 by 78.

Moving on to step 1:
78 can be fit into 2 0 times, resulting in 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.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 78

Let's proceed to step 2:
78 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 78

Advancing to step 3:
78 can be fit into 239 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 234 away from 239, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 78

Advancing to step 4:
59 divided by 78 is 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 59, we end up with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 78

Going ahead to step 5:
The number 78 fits into 597 7 times, leaving a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 307.0
Deduct 546 from 597 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 78

Advancing to step 6:
The number 78 fits into 519 6 times, leaving a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 3076.0
The remainder is 51 after subtracting 468 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
If we divide 510 by 78, we get 6 and a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 3076.6
Subtracting 468 from 510 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.

Let's proceed to step 8:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3076.65
If we take 390 away from 420, we end up 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.

Going ahead to step 9:
78 goes into 300 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 3076.653
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 3076.6538
Subtract 624 from 660 to 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.

Going ahead to step 11:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 3076.65384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3076.653846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3076.6538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3076.65384615
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.

Our division results in 3076.65384615 with a remaining 3e-08.
