543686 ÷ 85 
We want to divide 543686 by 85.

Going ahead to step 1:
85 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 85

Let's proceed to step 2:
54 divided by 85 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 85

Going ahead to step 3:
543 divided by 85 is 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 510 from 543 to get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 85

On to step 4:
85 goes into 336 3 times with a remainder of 81.
The next digit of our result is 3. 
Result so far: 63.0
Subtracting 255 from 336 leaves us with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 85

Step 5:
When dividing 818 by 85, we get 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Deduct 765 from 818 and we're left with 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 85

Let's proceed to step 6:
The number 85 fits into 536 6 times, leaving a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 6396.0
The remainder is 26 after subtracting 510 from 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 85, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 6396.3
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
85 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6396.3
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6396.305
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 6396.3058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
The number 85 fits into 700 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 6396.30588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 6396.30588, with a leftover of 2e-05.
