We look at the division of 606396 by 78 
Let's see how many times 78 fits into 606396.

Going ahead to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 78

Going ahead to step 2:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 78

On to step 3:
78 can be fit into 606 7 times, resulting in a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 546 from 606, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 78

Moving on to step 4:
78 can be fit into 603 7 times, resulting in a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 57 after subtracting 546 from 603.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 78

Let's proceed to step 5:
When dividing 579 by 78, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 777.0
Subtracting 546 from 579 leaves us with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 78

On to step 6:
336 divided by 78 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 7774.0
Subtract 312 from 336 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 78, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 7774.3
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 78, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7774.3
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
78 goes into 600 7 times with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7774.307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
If we divide 540 by 78, we get 6 and a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 7774.3076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 7774.30769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 7774.307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 7774.3076923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7774.3076923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7774.3076923 with a remainder of 6e-08.
