763821 divided by 87 
Let's see how many times 87 fits into 763821.

Step 1:
7 divided by 87 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 87

Advancing to step 2:
87 can be fit into 76 0 times, resulting in a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 87

Step 3:
763 divided by 87 is 8 with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 696 from 763 to get 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 87

Advancing to step 4:
87 can be fit into 678 7 times, resulting in a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 69 after subtracting 609 from 678.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 87

Moving on to step 5:
87 can be fit into 692 7 times, resulting in a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 877.0
If we subtract 609 from 692, we get 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 87

On to step 6:
When dividing 831 by 87, we get 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 8779.0
If we subtract 783 from 831, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 8779.5
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8779.55
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 8779.55 with a balance of 0.015.
