259681 ÷ 78 
We're looking to find how many times 78 goes into 259681.

On to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 78

On to step 2:
78 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 78

Moving on to step 3:
If we divide 259 by 78, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 234 from 259, we get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 78

Advancing to step 4:
When dividing 256 by 78, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 234 from 256, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 78

Step 5:
78 can be fit into 228 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 332.0
Subtract 156 from 228 to get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 78

Going ahead to step 6:
78 can be fit into 721 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 3329.0
Subtract 702 from 721 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 78 fits into 190 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 3329.2
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
If we divide 340 by 78, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 3329.24
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
When dividing 280 by 78, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3329.243
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 78, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 3329.2435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 3329.24358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
78 goes into 760 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 3329.243589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 3329.2435897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
340 divided by 78 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 3329.24358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 3329.24358974, with a leftover of 2.8e-08.
