263511 divided by 78 
We want to figure out the number of times 263511 can be divided by 78.

Moving on to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 78

Let's proceed to step 2:
The number 78 fits into 26 0 times, leaving a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 78

Advancing to step 3:
263 divided by 78 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 234 from 263, we get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 78

Step 4:
If we divide 295 by 78, we get 3 and a remainder of 61.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 234 from 295 and we're left with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 78

On to step 5:
If we divide 611 by 78, we get 7 and a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 337.0
If we subtract 546 from 611, we get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 78

Let's proceed to step 6:
The number 78 fits into 651 8 times, leaving a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 3378.0
The remainder is 27 after subtracting 624 from 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 78, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 3378.3
If we take 234 away from 270, 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.

Let's proceed to step 8:
If we divide 360 by 78, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 3378.34
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.

Step 9:
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: 3378.346
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.

Let's proceed to step 10:
When dividing 120 by 78, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 3378.3461
Deduct 78 from 120 and we're left 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 11:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 3378.34615
Subtracting 390 from 420 leaves us 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.

Step 12:
If we divide 300 by 78, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 3378.346153
Subtract 234 from 300 to 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.

Step 13:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 3378.3461538
Deduct 624 from 660 and we're left 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.

Moving on to step 14:
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: 3378.34615384
If we take 312 away from 360, we end up 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.

The final outcome is 3378.34615384, with a leftover of 4.8e-08.
