We're dividing 648348 by 78 
We want to divide 648348 by 78.

Going ahead to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 78

On to step 2:
When dividing 64 by 78, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 78

Advancing to step 3:
If we divide 648 by 78, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 624 from 648 and we're left with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 78

Step 4:
The number 78 fits into 243 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 83.0
The remainder is 9 after subtracting 234 from 243.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 78

Going ahead to step 5:
If we divide 94 by 78, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 831.0
If we subtract 78 from 94, we get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 78

Going ahead to step 6:
168 divided by 78 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 8312.0
The remainder is 12 after subtracting 156 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 78, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 8312.1
Subtract 78 from 120 to get 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 8:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 8312.15
Deduct 390 from 420 and we're left 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 9:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 8312.153
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.

Moving on to step 10:
When dividing 660 by 78, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8312.1538
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.

Advancing to step 11:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 8312.15384
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.

Let's proceed to step 12:
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: 8312.153846
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 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 8312.1538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
When dividing 420 by 78, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 8312.15384615
Deduct 390 from 420 and we're left 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.

The quotient of the division is 8312.15384615, and the remainder is 3e-08.
