We look at the division of 638068 by 78 
We want to figure out the number of times 638068 can be divided by 78.

Let's proceed to step 1:
78 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 78

Let's proceed to step 2:
78 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 78

Moving on to step 3:
If we divide 638 by 78, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 638 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 78

Step 4:
The number 78 fits into 140 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 78 from 140 leaves us with 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 78

On to step 5:
When dividing 626 by 78, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
If we take 624 away from 626, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 78

Going ahead to step 6:
When dividing 28 by 78, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 8180.0
The remainder is 28 after subtracting 0 from 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 7:
When dividing 280 by 78, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 8180.3
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.

Going ahead to step 8:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8180.35
Subtracting 390 from 460 leaves us 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 9:
78 goes into 700 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 8180.358
Deduct 624 from 700 and we're left 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.

Moving on to step 10:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 8180.3589
If we subtract 702 from 760, we 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.

Going ahead to step 11:
580 divided by 78 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 8180.35897
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.

Advancing to step 12:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 8180.358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
78 goes into 280 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 8180.3589743
Subtracting 234 from 280 leaves us 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.

Advancing to step 14:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8180.35897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 8180.35897435 and a remainder of 7e-08.
