352389 ÷ 87 
We want to figure out the number of times 352389 can be divided by 87.

Let's proceed 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
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 87

Step 2:
87 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 87

Let's proceed to step 3:
87 goes into 352 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 348 from 352 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 87

Let's proceed to step 4:
43 divided by 87 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 87

On to step 5:
If we divide 438 by 87, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 405.0
Subtract 435 from 438 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 87

Step 6:
The number 87 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 4050.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 4050.4
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 87, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4050.44
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 4050.44, with a leftover of 0.072.
