646184 divided by 84 
We want to divide 646184 by 84.

On to step 1:
6 divided by 84 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 84

Going ahead to step 2:
When dividing 64 by 84, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 84

Moving on to step 3:
84 can be fit into 646 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 58 after subtracting 588 from 646.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 84

Moving on to step 4:
84 can be fit into 581 6 times, resulting in a remainder of 77.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 504 from 581 to get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 84

Step 5:
84 can be fit into 778 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 769.0
Subtracting 756 from 778 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 84

Going ahead to step 6:
If we divide 224 by 84, we get 2 and a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 7692.0
Deduct 168 from 224 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
If we divide 560 by 84, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 7692.6
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
When dividing 560 by 84, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 7692.66
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 7692.66 with a remainder of 0.056.
