810307 ÷ 84 
Let's see how many times 84 fits into 810307.

Step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 84

Going ahead to step 2:
81 divided by 84 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 84

Going ahead to step 3:
When dividing 810 by 84, we get 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 756 away from 810, we end up with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 84

Going ahead to step 4:
If we divide 543 by 84, we get 6 and a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtracting 504 from 543 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 84

Step 5:
When dividing 390 by 84, we get 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 964.0
Subtract 336 from 390 to get 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 84

Going ahead to step 6:
When dividing 547 by 84, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 9646.0
Deduct 504 from 547 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
If we divide 430 by 84, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9646.5
Subtracting 420 from 430 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 84 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 9646.51
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
If we divide 160 by 84, we get 1 and a remainder of 76.
The next digit of our result is 1. 
Result so far: 9646.511
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 9646.511 with a balance of 0.0076.
