We divide 623992 by 78
We want to divide 623992 by 78.

Going ahead to step 1:
If we divide 6 by 78, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 78

Moving on to step 2:
78 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 78

Advancing to step 3:
When dividing 623 by 78, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 546 from 623 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 78

Moving on to step 4:
779 divided by 78 is 9 with a remainder of 77.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 77 after subtracting 702 from 779.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 78

Step 5:
779 divided by 78 is 9 with a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 799.0
Subtract 702 from 779 to get 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 78

On to step 6:
The number 78 fits into 772 9 times, leaving a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 7999.0
Subtract 702 from 772 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.

Moving on to step 7:
78 goes into 700 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 7999.8
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.

Step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 7999.89
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 9:
78 goes into 580 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7999.897
If we take 546 away from 580, we end up 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.

Let's proceed to step 10:
78 goes into 340 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 7999.8974
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.

Step 11:
280 divided by 78 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 7999.89743
Deduct 234 from 280 and we're left 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.

Let's proceed to step 12:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 7999.897435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 7999.8974358
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.

Going ahead to step 14:
If we divide 760 by 78, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 7999.89743589
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.

Our division results in 7999.89743589 with a remaining 5.8e-08.
