342506 ÷ 87 
Let's see how many times 87 fits into 342506.

Going ahead to step 1:
3 divided by 87 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 87

Step 2:
If we divide 34 by 87, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 87

Let's proceed to step 3:
87 can be fit into 342 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 81 after subtracting 261 from 342.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 87

Let's proceed to step 4:
The number 87 fits into 815 9 times, leaving a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 783 away from 815, we end up with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 87

On to step 5:
When dividing 320 by 87, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 393.0
If we take 261 away from 320, we end up with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 87

Going ahead to step 6:
596 divided by 87 is 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 3936.0
Subtracting 522 from 596 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
87 goes into 740 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 3936.8
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
440 divided by 87 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3936.85
If we take 435 away from 440, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 87 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3936.85
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 87 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 3936.8505
Subtract 435 from 500 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
The number 87 fits into 650 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 3936.85057
If we take 609 away from 650, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
410 divided by 87 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 3936.850574
If we take 348 away from 410, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
When dividing 620 by 87, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 3936.8505747
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
87 can be fit into 110 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 3936.85057471
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 3936.85057471, with a leftover of 2.3e-08.
