We look at the division of 4507802 by 78 
Our goal is to divide 4507802 by 78.

Step 1:
78 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 78

Advancing to step 2:
78 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 78

Advancing to step 3:
The number 78 fits into 450 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 60 after subtracting 390 from 450.
Bring next digit (7) of the dividend behind the 60 and repeat the process: 607 / 78

Advancing to step 4:
607 divided by 78 is 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we subtract 546 from 607, we get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 78

Going ahead to step 5:
618 divided by 78 is 7 with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 577.0
Subtract 546 from 618 to get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 78

Advancing to step 6:
720 divided by 78 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 5779.0
Subtract 702 from 720 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 78

On to step 7:
78 goes into 182 2 times with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 57792.0
Deduct 156 from 182 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
If we divide 260 by 78, we get 3 and a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 57792.3
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 78 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 57792.33
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 57792.33, with a leftover of 0.026.
