577857 ÷ 84 
Let's see how many times 84 fits into 577857.

On to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 84

Going ahead to step 2:
57 divided by 84 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 84

Let's proceed to step 3:
If we divide 577 by 84, we get 6 and a remainder of 73.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 73 after subtracting 504 from 577.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 84

On to step 4:
738 divided by 84 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 66 after subtracting 672 from 738.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 84

Step 5:
If we divide 665 by 84, we get 7 and a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 687.0
Subtracting 588 from 665 leaves us with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 84

Step 6:
If we divide 777 by 84, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 6879.0
The remainder is 21 after subtracting 756 from 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
84 can be fit into 210 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 6879.2
The remainder is 42 after subtracting 168 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 84 fits into 420 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6879.25
If we take 420 away from 420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 84, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6879.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 84, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6879.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 6879.25 with a remainder of 0.0.
