We look at the division of 518646 by 84 
Let's see how many times 84 fits into 518646.

Going ahead to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 84

On to step 2:
51 divided by 84 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 84

Moving on to step 3:
If we divide 518 by 84, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 504 away from 518, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 84

On to step 4:
84 goes into 146 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 62 after subtracting 84 from 146.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 84

Let's proceed to step 5:
84 can be fit into 624 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 617.0
Subtracting 588 from 624 leaves us with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 84

Going ahead to step 6:
The number 84 fits into 366 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 6174.0
If we take 336 away from 366, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
84 goes into 300 3 times with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 6174.3
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 6174.35
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 6174.357
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 6174.3571
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 6174.35714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 84 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 6174.357142
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 84 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 6174.3571428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
84 goes into 480 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 6174.35714285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 6174.35714285, with a leftover of 6e-08.
