We look at the division of 873983 by 84 
We're looking to find how many times 84 goes into 873983.

Advancing to step 1:
The number 84 fits into 8 0 times, leaving 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.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 84

Step 2:
If we divide 87 by 84, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 84 from 87 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 84

Moving on to step 3:
33 divided by 84 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 84

Let's proceed to step 4:
The number 84 fits into 339 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 336 from 339 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 84

Going ahead to step 5:
84 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 84

Moving on to step 6:
84 goes into 383 4 times with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 10404.0
Deduct 336 from 383 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
470 divided by 84 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10404.5
Subtracting 420 from 470 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
The number 84 fits into 500 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 10404.55
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 10404.55, and the remainder is 0.08.
