We look at the division of 664914 by 78 
We want to figure out the number of times 664914 can be divided by 78.

Step 1:
6 divided by 78 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 78

Going ahead to step 2:
78 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 78

Step 3:
78 can be fit into 664 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 624 from 664, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 78

Step 4:
78 can be fit into 409 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 390 from 409, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 78

Step 5:
78 can be fit into 191 2 times, resulting in a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 852.0
If we take 156 away from 191, we end up with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 78

Advancing to step 6:
When dividing 354 by 78, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 8524.0
If we take 312 away from 354, we end up 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.

Let's proceed to step 7:
If we divide 420 by 78, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8524.5
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 8:
When dividing 300 by 78, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 8524.53
Subtracting 234 from 300 leaves us 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 9:
660 divided by 78 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 8524.538
Subtract 624 from 660 to 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.

Moving on to step 10:
If we divide 360 by 78, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 8524.5384
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.

Let's proceed to step 11:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 8524.53846
Deduct 468 from 480 and we're left 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.

Going ahead to step 12:
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: 8524.538461
If we take 78 away from 120, we end up 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.

Going ahead to step 13:
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: 8524.5384615
If we subtract 390 from 420, we 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.

Moving on to step 14:
If we divide 300 by 78, we get 3 and a remainder of 66.
The next digit of our result is 3. 
Result so far: 8524.53846153
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.

In conclusion, the division gives 8524.53846153 with a balance of 6.6e-08.
