684478 divided by 78 
We're looking to find how many times 78 goes into 684478.

Step 1:
78 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 78

On to step 2:
78 can be fit into 68 0 times, resulting in a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 78

Going ahead to step 3:
78 goes into 684 8 times with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 624 away from 684, we end up with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 78

Step 4:
78 can be fit into 604 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 546 away from 604, we end up with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 78

Moving on to step 5:
78 can be fit into 587 7 times, resulting in a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
Subtracting 546 from 587 leaves us with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 78

Advancing to step 6:
If we divide 418 by 78, we get 5 and a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 8775.0
Subtract 390 from 418 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 78, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 8775.3
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8775.35
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
When dividing 700 by 78, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8775.358
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 8775.3589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
580 divided by 78 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 8775.35897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 8775.358974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 8775.3589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
If we divide 460 by 78, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 8775.35897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 8775.35897435 with a remaining 7e-08.
