We're dividing 638896 by 78 
We want to figure out the number of times 638896 can be divided by 78.

Advancing 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
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 78

Step 2:
If we divide 63 by 78, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 78

Moving on to step 3:
When dividing 638 by 78, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 14 after subtracting 624 from 638.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 78

Going ahead to step 4:
The number 78 fits into 148 1 times, leaving a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 70 after subtracting 78 from 148.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 78

Step 5:
78 can be fit into 709 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 819.0
Deduct 702 from 709 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 78

Going ahead to step 6:
If we divide 76 by 78, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 8190.0
Subtracting 0 from 76 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 7:
When dividing 760 by 78, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 8190.9
Subtracting 702 from 760 leaves us 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.

Let's proceed to step 8:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 8190.97
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 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 8190.974
Subtracting 312 from 340 leaves us 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.

Moving on to step 10:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 8190.9743
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.

Going ahead to step 11:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 8190.97435
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.

On to step 12:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8190.974358
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.

Step 13:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 8190.9743589
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.

Advancing to step 14:
78 goes into 580 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 8190.97435897
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 8190.97435897 with a remaining 3.4e-08.
