405456 ÷ 87 
We're looking to find how many times 87 goes into 405456.

On to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 87

On to step 2:
40 divided by 87 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 87

On to step 3:
The number 87 fits into 405 4 times, leaving a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 348 from 405 to get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 87

Going ahead to step 4:
574 divided by 87 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 522 from 574, we get 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 87

Step 5:
If we divide 525 by 87, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 466.0
If we take 522 away from 525, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 87

Advancing to step 6:
87 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 4660.0
Subtracting 0 from 36 leaves us 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.

On to step 7:
If we divide 360 by 87, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4660.4
If we take 348 away from 360, we end up 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.

Let's proceed to step 8:
If we divide 120 by 87, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 4660.41
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
330 divided by 87 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 4660.413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
87 can be fit into 690 7 times, resulting in a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 4660.4137
Subtract 609 from 690 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 11:
When dividing 810 by 87, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 4660.41379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
87 goes into 270 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 4660.413793
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 87 fits into 90 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 4660.4137931
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4660.4137931
Deduct 0 from 30 and we're left 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.

In conclusion, the division gives 4660.4137931 with a balance of 3e-08.
