579809 divided by 84 
Our goal is to divide 579809 by 84.

Step 1:
If we divide 5 by 84, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 84

Going ahead to step 2:
84 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 84

Moving on to step 3:
84 can be fit into 579 6 times, resulting in a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 504 away from 579, we end up with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 84

Let's proceed to step 4:
84 can be fit into 758 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we subtract 756 from 758, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 84

On to step 5:
20 divided by 84 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 690.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 84

On to step 6:
84 goes into 209 2 times with a remainder of 41.
The next digit of our result is 2. 
Result so far: 6902.0
The remainder is 41 after subtracting 168 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
When dividing 410 by 84, we get 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 6902.4
Deduct 336 from 410 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
If we divide 740 by 84, we get 8 and a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 6902.48
Subtracting 672 from 740 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
680 divided by 84 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6902.488
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 6902.488 and a remainder of 0.0008.
