342235 ÷ 87 
Our goal is to divide 342235 by 87.

Advancing to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 87

Going ahead to step 2:
87 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 87

Moving on to step 3:
87 goes into 342 3 times with a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 261 from 342 to get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 87

Step 4:
When dividing 812 by 87, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 783 from 812 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 87

Let's proceed to step 5:
87 can be fit into 293 3 times, resulting in a remainder of 32.
The next digit of our result is 3. 
Result so far: 393.0
Subtract 261 from 293 to get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 87

Moving on to step 6:
87 can be fit into 325 3 times, resulting in a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 3933.0
If we subtract 261 from 325, we 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.

Let's proceed to step 7:
87 can be fit into 640 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 3933.7
If we subtract 609 from 640, we 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.

Going ahead to step 8:
When dividing 310 by 87, we get 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 3933.73
The remainder is 49 after subtracting 261 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 87, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 3933.735
Subtract 435 from 490 to get 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 10:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 3933.7356
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
When dividing 280 by 87, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3933.73563
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
The number 87 fits into 190 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 3933.735632
If we subtract 174 from 190, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
87 goes into 160 1 times with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 3933.7356321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
When dividing 730 by 87, we get 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 3933.73563218
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 3933.73563218 with a remainder of 3.4e-08.
