343522 divided by 87 
Let's see how many times 87 fits into 343522.

Advancing to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 87

Moving on to step 2:
The number 87 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 87

Let's proceed to step 3:
The number 87 fits into 343 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 82 after subtracting 261 from 343.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 87

Step 4:
The number 87 fits into 825 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 783 from 825 leaves us with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 87

Let's proceed to step 5:
422 divided by 87 is 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
If we subtract 348 from 422, we get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 87

Going ahead to step 6:
742 divided by 87 is 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 3948.0
Deduct 696 from 742 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
If we divide 460 by 87, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3948.5
If we subtract 435 from 460, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
When dividing 250 by 87, we get 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 3948.52
The remainder is 76 after subtracting 174 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
If we divide 760 by 87, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 3948.528
Subtract 696 from 760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 87, we get 7 and a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 3948.5287
Subtract 609 from 640 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
310 divided by 87 is 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 3948.52873
Deduct 261 from 310 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
If we divide 490 by 87, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 3948.528735
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
If we divide 550 by 87, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 3948.5287356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
When dividing 280 by 87, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3948.52873563
The remainder is 19 after subtracting 261 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 3948.52873563 with a remainder of 1.9e-08.
