Let's divide 784086 by 78
Let's see how many times 78 fits into 784086.

Going ahead to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 78

Going ahead to step 2:
The number 78 fits into 78 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 78 from 78, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 78

Step 3:
78 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 78

Moving on to step 4:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 78

Let's proceed to step 5:
78 goes into 408 5 times with a remainder of 18.
The next digit of our result is 5. 
Result so far: 1005.0
The remainder is 18 after subtracting 390 from 408.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 78

Going ahead to step 6:
78 goes into 186 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 10052.0
Subtracting 156 from 186 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.

Moving on to step 7:
78 goes into 300 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 10052.3
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.

On to step 8:
660 divided by 78 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 10052.38
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.

Advancing to step 9:
When dividing 360 by 78, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10052.384
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.

On to step 10:
If we divide 480 by 78, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 10052.3846
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:
If we divide 120 by 78, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 10052.38461
The remainder is 42 after subtracting 78 from 120.
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:
When dividing 420 by 78, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10052.384615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 10052.3846153
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.

Advancing to step 14:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 10052.38461538
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.

The quotient of the division is 10052.38461538, and the remainder is 3.6e-08.
