We look at the division of 807257 by 78 
We want to figure out the number of times 807257 can be divided by 78.

Going ahead to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 78

Step 2:
80 divided by 78 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 80 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 78

Let's proceed to step 3:
If we divide 27 by 78, we get 0 and a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 27 leaves us with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 78

Advancing to step 4:
When dividing 272 by 78, we get 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 234 from 272 to get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 78

Moving on to step 5:
When dividing 385 by 78, we get 4 with a remainder of 73.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
The remainder is 73 after subtracting 312 from 385.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 78

Step 6:
The number 78 fits into 737 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 10349.0
Subtracting 702 from 737 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
78 can be fit into 350 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 10349.4
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
If we divide 380 by 78, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 10349.44
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 10349.44 with a remainder of 0.068.
