Let's divide 815311 by 84
We're looking to find how many times 84 goes into 815311.

On to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
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

Let's proceed to step 2:
84 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 84

On to step 3:
815 divided by 84 is 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 756 from 815 to get 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 84

Advancing to step 4:
593 divided by 84 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 588 from 593, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 84

Step 5:
51 divided by 84 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 970.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 84

Advancing to step 6:
The number 84 fits into 511 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 9706.0
Deduct 504 from 511 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 84 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 9706.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
When dividing 700 by 84, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 9706.08
If we subtract 672 from 700, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 84, we get 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 9706.083
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
84 goes into 280 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 9706.0833
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 9706.0833, and the remainder is 0.00028.
