543524 ÷ 87 
Let's see how many times 87 fits into 543524.

Going ahead to step 1:
The number 87 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
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 87

Step 2:
When dividing 54 by 87, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 87

Step 3:
If we divide 543 by 87, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 522 away from 543, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 87

Let's proceed to step 4:
87 can be fit into 215 2 times, resulting in a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 174 away from 215, we end up with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 87

Let's proceed to step 5:
87 goes into 412 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 624.0
If we take 348 away from 412, we end up with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 87

Step 6:
87 can be fit into 644 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 6247.0
If we subtract 609 from 644, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 87, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 6247.4
The remainder is 2 after subtracting 348 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 87 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 6247.4
If we take 0 away from 20, we end up 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.

Going ahead to step 9:
87 goes into 200 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 6247.402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
87 goes into 260 2 times with a remainder of 86.
The next digit of our result is 2. 
Result so far: 6247.4022
The remainder is 86 after subtracting 174 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 6247.4022 with a remainder of 0.00086.
