191019 ÷ 78 
Let's see how many times 78 fits into 191019.

Let's proceed to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 78

Let's proceed to step 2:
If we divide 19 by 78, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 78

Moving on to step 3:
When dividing 191 by 78, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 156 away from 191, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 78

Step 4:
If we divide 350 by 78, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 312 from 350 to get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 78

On to step 5:
The number 78 fits into 381 4 times, leaving a remainder of 69.
The next digit of our result is 4. 
Result so far: 244.0
If we take 312 away from 381, we end up with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 78

On to step 6:
78 goes into 699 8 times with a remainder of 75.
The next digit of our result is 8. 
Result so far: 2448.0
Subtracting 624 from 699 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 7:
78 goes into 750 9 times with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 2448.9
If we subtract 702 from 750, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
480 divided by 78 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2448.96
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 9:
78 can be fit into 120 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 2448.961
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.

On to step 10:
78 can be fit into 420 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2448.9615
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.

On to step 11:
78 goes into 300 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 2448.96153
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.

On to step 12:
78 goes into 660 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 2448.961538
If we subtract 624 from 660, we 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.

Step 13:
When dividing 360 by 78, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 2448.9615384
Subtracting 312 from 360 leaves us 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.

On to step 14:
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: 2448.96153846
If we take 468 away from 480, we end up 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.

Our division results in 2448.96153846 with a remaining 1.2e-08.
