43995 ÷ 84 
We want to figure out the number of times 43995 can be divided by 84.

Step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 84

On to step 2:
The number 84 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 84

Going ahead to step 3:
84 can be fit into 439 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 420 from 439 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 84

On to step 4:
If we divide 199 by 84, we get 2 and a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 168 from 199 to get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 84

Going ahead to step 5:
84 goes into 315 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 523.0
Subtracting 252 from 315 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 6:
The number 84 fits into 630 7 times, leaving a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 523.7
Subtracting 588 from 630 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 84 fits into 420 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 523.75
The remainder is 0 after subtracting 420 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 84, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 523.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 84 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 523.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 523.75, and the remainder is 0.0.
