We're dividing 654808 by 78 
We want to divide 654808 by 78.

Step 1:
78 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 78

Going ahead to step 2:
78 can be fit into 65 0 times, resulting in a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 78

On to step 3:
When dividing 654 by 78, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 624 away from 654, we end up with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 78

Step 4:
If we divide 308 by 78, we get 3 and a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 234 from 308 leaves us with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 78

Let's proceed to step 5:
When dividing 740 by 78, we get 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 839.0
The remainder is 38 after subtracting 702 from 740.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 78

On to step 6:
78 can be fit into 388 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 8394.0
Subtract 312 from 388 to 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 7:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 8394.9
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
When dividing 580 by 78, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 8394.97
Subtract 546 from 580 to 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.

Advancing to step 9:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 8394.974
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.

Let's proceed to step 10:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 8394.9743
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.

Step 11:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8394.97435
If we subtract 390 from 460, we 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.

Step 12:
78 goes into 700 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 8394.974358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 8394.9743589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 8394.97435897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 8394.97435897, with a leftover of 3.4e-08.
