81224868 ÷ 78 
We want to figure out the number of times 81224868 can be divided by 78.

Going ahead to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 78

Going ahead to step 2:
The number 78 fits into 81 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 81 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 78

Step 3:
When dividing 32 by 78, we get 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 78

Step 4:
The number 78 fits into 322 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 104.0
Subtract 312 from 322 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 78

Let's proceed to step 5:
104 divided by 78 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1041.0
If we take 78 away from 104, we end up with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 78

Going ahead to step 6:
78 goes into 268 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 10413.0
Deduct 234 from 268 and we're left with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 78

On to step 7:
346 divided by 78 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 104134.0
If we subtract 312 from 346, we get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 78

Let's proceed to step 8:
78 can be fit into 348 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1041344.0
The remainder is 36 after subtracting 312 from 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 78, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1041344.4
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.

Moving on to step 10:
480 divided by 78 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1041344.46
Subtracting 468 from 480 leaves us 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.

Step 11:
78 goes into 120 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1041344.461
Subtracting 78 from 120 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.

Moving on to step 12:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1041344.4615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
78 goes into 300 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 1041344.46153
The remainder is 66 after subtracting 234 from 300.
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 14:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 1041344.461538
Subtracting 624 from 660 leaves us 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 15:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 1041344.4615384
Subtract 312 from 360 to 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.

On to step 16:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1041344.46153846
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.

In conclusion, the division gives 1041344.46153846 with a balance of 1.2e-08.
