We look at the division of 623688 by 78 
We want to figure out the number of times 623688 can be divided by 78.

Advancing to step 1:
78 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 78

Moving on to step 2:
78 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 78

On to step 3:
623 divided by 78 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 546 from 623, we get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 78

Advancing to step 4:
78 can be fit into 776 9 times, resulting in a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 702 from 776, we get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 78

Step 5:
748 divided by 78 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Deduct 702 from 748 and we're left with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 78

Moving on to step 6:
If we divide 468 by 78, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 7996.0
Subtract 468 from 468 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7996.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
78 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7996.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7996.0, and the remainder is 0.0.
