We're dividing 344534 by 87 
Let's see how many times 87 fits into 344534.

Step 1:
3 divided by 87 is 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.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 87

Advancing to step 2:
87 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 87

Going ahead to step 3:
87 goes into 344 3 times with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 261 from 344 to get 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 87

Moving on to step 4:
87 can be fit into 835 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 52 after subtracting 783 from 835.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 87

Advancing to step 5:
87 goes into 523 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
Subtracting 522 from 523 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 87

On to step 6:
When dividing 14 by 87, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 3960.0
If we subtract 0 from 14, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
87 goes into 140 1 times with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 3960.1
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
If we divide 530 by 87, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3960.16
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 87, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 3960.16
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
87 goes into 800 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 3960.1609
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
If we divide 170 by 87, we get 1 and a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 3960.16091
Deduct 87 from 170 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
830 divided by 87 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 3960.160919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
When dividing 470 by 87, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3960.1609195
If we subtract 435 from 470, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
87 can be fit into 350 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3960.16091954
Subtract 348 from 350 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 3960.16091954, with a leftover of 2e-09.
