We're dividing 73015255 by 770 
Our goal is to divide 73015255 by 770.

On to step 1:
If we divide 7 by 770, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 770

Moving on to step 2:
770 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 770

Advancing to step 3:
770 can be fit into 730 0 times, resulting in a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 730 leaves us with 730.
Take the next digit (1) from the dividend and append it to 730, then repeat: 7301 / 770

Going ahead to step 4:
7301 divided by 770 is 9 with a remainder of 371.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6930 from 7301, we get 371.
Append the next digit (5) from the dividend to 371 and continue with: 3715 / 770

Advancing to step 5:
When dividing 3715 by 770, we get 4 with a remainder of 635.
The next digit of our result is 4. 
Result so far: 94.0
If we take 3080 away from 3715, we end up with 635.
Bring next digit (2) of the dividend behind the 635 and repeat the process: 6352 / 770

On to step 6:
If we divide 6352 by 770, we get 8 and a remainder of 192.
The next digit of our result is 8. 
Result so far: 948.0
If we take 6160 away from 6352, we end up with 192.
Fetch the next digit (5) from the dividend, attach it to 192 and continue: 1925 / 770

Advancing to step 7:
770 goes into 1925 2 times with a remainder of 385.
Use 2 as the next digit of our solution. 
Result so far: 9482.0
Subtracting 1540 from 1925 leaves us with 385.
Take the next digit (5) from the dividend and append it to 385, then repeat: 3855 / 770

Going ahead to step 8:
When dividing 3855 by 770, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 94825.0
The remainder is 5 after subtracting 3850 from 3855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
770 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 94825.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 770 fits into 500 0 times, leaving a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 94825.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 94825.0, and the remainder is 0.5.
