We look at the division of 771555 by 30 
Let's see how many times 30 fits into 771555.

Advancing to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 30

Moving on to step 2:
When dividing 77 by 30, we get 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 60 from 77 leaves us with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 30

Advancing to step 3:
If we divide 171 by 30, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 21 after subtracting 150 from 171.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 30

Moving on to step 4:
When dividing 215 by 30, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 257.0
If we subtract 210 from 215, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 30

Moving on to step 5:
55 divided by 30 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 2571.0
Deduct 30 from 55 and we're left with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 30

On to step 6:
When dividing 255 by 30, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 25718.0
Subtracting 240 from 255 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
30 goes into 150 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25718.5
The remainder is 0 after subtracting 150 from 150.
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:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25718.5
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.

Advancing to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25718.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 25718.5 and a remainder of 0.0.
