We're dividing 543190 by 84 
We want to figure out the number of times 543190 can be divided by 84.

Going ahead to step 1:
The number 84 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 84

On to step 2:
84 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 84

Advancing to step 3:
84 can be fit into 543 6 times, resulting in a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 504 from 543 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 84

Moving on to step 4:
84 goes into 391 4 times with a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 55 after subtracting 336 from 391.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 84

Advancing to step 5:
If we divide 559 by 84, we get 6 and a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 646.0
Subtract 504 from 559 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 84

Let's proceed to step 6:
If we divide 550 by 84, we get 6 and a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 6466.0
If we subtract 504 from 550, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
84 can be fit into 460 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 6466.5
Deduct 420 from 460 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 84 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 6466.54
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
84 goes into 640 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 6466.547
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
If we divide 520 by 84, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6466.5476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
84 goes into 160 1 times with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 6466.54761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 6466.547619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
84 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6466.547619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 84, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 6466.54761904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 6466.54761904, with a leftover of 6.4e-08.
