We look at the division of 849709 by 84 
We want to figure out the number of times 849709 can be divided by 84.

Step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 84

On to step 2:
If we divide 84 by 84, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 84 from 84 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 84

Going ahead to step 3:
If we divide 9 by 84, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 84

On to step 4:
If we divide 97 by 84, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 84 from 97 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 84

Let's proceed to step 5:
The number 84 fits into 130 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 1011.0
If we subtract 84 from 130, we get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 84

Advancing to step 6:
The number 84 fits into 469 5 times, leaving a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 10115.0
Deduct 420 from 469 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 84 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10115.5
The remainder is 70 after subtracting 420 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 84, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 10115.58
If we take 672 away from 700, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
84 can be fit into 280 3 times, resulting in a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 10115.583
Subtracting 252 from 280 leaves us with 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 10:
84 goes into 280 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 10115.5833
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.

The final result is 10115.5833 with a remainder of 0.00028.
