We look at the division of 807385 by 78 
We're looking to find how many times 78 goes into 807385.

Step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 78

Step 2:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 78 away from 80, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 78

Advancing to step 3:
When dividing 27 by 78, we get 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 27 leaves us with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 78

Going ahead to step 4:
When dividing 273 by 78, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 234 from 273 leaves us with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 78

Moving on to step 5:
When dividing 398 by 78, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 1035.0
Deduct 390 from 398 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 78

Let's proceed to step 6:
78 can be fit into 85 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 10351.0
If we take 78 away from 85, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 78 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10351.0
Deduct 0 from 70 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.

Moving on to step 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 10351.08
Subtract 624 from 700 to get 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 9:
When dividing 760 by 78, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 10351.089
Deduct 702 from 760 and we're left 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.

Step 10:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 10351.0897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 10351.08974
Deduct 312 from 340 and we're left 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.

Let's proceed to step 12:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 10351.089743
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.

Moving on to step 13:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10351.0897435
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 14:
700 divided by 78 is 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 10351.08974358
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 10351.08974358 with a remainder of 7.6e-08.
