Let's divide 647724 by 78
We're looking to find how many times 78 goes into 647724.

On to step 1:
6 divided by 78 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 78

Moving on to step 2:
78 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 78

Going ahead to step 3:
647 divided by 78 is 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 624 away from 647, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 78

Let's proceed to step 4:
78 goes into 237 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 3 after subtracting 234 from 237.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 78

Let's proceed to step 5:
32 divided by 78 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 830.0
If we subtract 0 from 32, we get 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 78

Let's proceed to step 6:
The number 78 fits into 324 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8304.0
If we subtract 312 from 324, 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.

Going ahead to step 7:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8304.1
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.

On to step 8:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8304.15
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.

Let's proceed to step 9:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 8304.153
Deduct 234 from 300 and we're left with 66.
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 10:
78 goes into 660 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 8304.1538
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.

Step 11:
78 goes into 360 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 8304.15384
If we subtract 312 from 360, 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 12:
When dividing 480 by 78, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8304.153846
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.

Going ahead to step 13:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 8304.1538461
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 14:
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: 8304.15384615
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 final outcome is 8304.15384615, with a leftover of 3e-08.
