We look at the division of 772809 by 5 
We want to divide 772809 by 5.

On to step 1:
The number 5 fits into 7 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 5 from 7.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 5

Going ahead to step 2:
5 can be fit into 27 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 25 from 27, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 5

Let's proceed to step 3:
If we divide 22 by 5, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Deduct 20 from 22 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 5

Moving on to step 4:
If we divide 28 by 5, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 1545.0
Subtracting 25 from 28 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 5

Advancing to step 5:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 15456.0
The remainder is 0 after subtracting 30 from 30.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Advancing to step 6:
When dividing 9 by 5, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 154561.0
Subtract 5 from 9 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 5, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 154561.8
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 154561.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 5 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 154561.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 154561.8 with a remainder of 0.0.
