We divide 87810311 by 728
Let's see how many times 728 fits into 87810311.

Going ahead to step 1:
728 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 728

Advancing to step 2:
When dividing 87 by 728, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 728

Going ahead to step 3:
The number 728 fits into 878 1 times, leaving a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 728 from 878, we get 150.
Take the next digit (1) from the dividend and append it to 150, then repeat: 1501 / 728

Let's proceed to step 4:
1501 divided by 728 is 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1456 from 1501, we get 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 728

Moving on to step 5:
The number 728 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 450 and we're left with 450.
Fetch the next digit (3) from the dividend, attach it to 450 and continue: 4503 / 728

Advancing to step 6:
If we divide 4503 by 728, we get 6 and a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 1206.0
Subtracting 4368 from 4503 leaves us with 135.
Grab the next digit (1) from the dividend, add it to 135, then carry on: 1351 / 728

Step 7:
When dividing 1351 by 728, we get 1 with a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 12061.0
If we take 728 away from 1351, we end up with 623.
Take the next digit (1) from the dividend and append it to 623, then repeat: 6231 / 728

Advancing to step 8:
If we divide 6231 by 728, we get 8 and a remainder of 407.
The number 8 becomes the next digit in our result. 
Result so far: 120618.0
If we take 5824 away from 6231, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 9:
728 can be fit into 4070 5 times, resulting in a remainder of 430.
The next digit of our result is 5. 
Result so far: 120618.5
The remainder is 430 after subtracting 3640 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 10:
If we divide 4300 by 728, we get 5 and a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 120618.55
Deduct 3640 from 4300 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 120618.55 with a balance of 0.66.
