623788 divided by 78 
We want to divide 623788 by 78.

On to step 1:
6 divided by 78 is 0 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.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 78

On to step 2:
If we divide 62 by 78, we get 0 and a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 78

Let's proceed to step 3:
623 divided by 78 is 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 546 away from 623, we end up with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 78

Advancing to step 4:
78 can be fit into 777 9 times, resulting in a remainder of 75.
The next digit of our result is 9. 
Result so far: 79.0
If we take 702 away from 777, we end up with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 78

Moving on to step 5:
The number 78 fits into 758 9 times, leaving a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Subtracting 702 from 758 leaves us with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 78

Step 6:
The number 78 fits into 568 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 7997.0
Subtract 546 from 568 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 7997.2
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
640 divided by 78 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7997.28
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 7997.282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7997.282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7997.28205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 7997.282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 78, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7997.2820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
When dividing 640 by 78, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7997.28205128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7997.28205128 and a remainder of 1.6e-08.
