260870 ÷ 78 
We want to divide 260870 by 78.

Advancing to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 78

Step 2:
78 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 78

Advancing to step 3:
260 divided by 78 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 234 from 260 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 78

Going ahead to step 4:
If we divide 268 by 78, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 234 from 268, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 78

Going ahead to step 5:
If we divide 347 by 78, we get 4 and a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
The remainder is 35 after subtracting 312 from 347.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 78

Going ahead to step 6:
78 goes into 350 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 3344.0
Subtract 312 from 350 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 7:
If we divide 380 by 78, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 3344.4
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
680 divided by 78 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 3344.48
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.

Step 9:
When dividing 560 by 78, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 3344.487
If we take 546 away from 560, we end up 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.

Advancing to step 10:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 3344.4871
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 11:
When dividing 620 by 78, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 3344.48717
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 12:
78 goes into 740 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 3344.487179
Subtracting 702 from 740 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 3344.4871794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 3344.48717948
Deduct 624 from 680 and we're left 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.

The final outcome is 3344.48717948, with a leftover of 5.6e-08.
