393026 ÷ 87 
Let's see how many times 87 fits into 393026.

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.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 87

Moving on to step 2:
87 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 87

On to step 3:
87 goes into 393 4 times with a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 45 after subtracting 348 from 393.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 87

Advancing to step 4:
450 divided by 87 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 435 from 450, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 87

Advancing to step 5:
152 divided by 87 is 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 451.0
Deduct 87 from 152 and we're left with 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 87

On to step 6:
When dividing 656 by 87, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 4517.0
If we take 609 away from 656, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
87 can be fit into 470 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4517.5
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.

Let's proceed to step 8:
87 can be fit into 350 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 4517.54
Deduct 348 from 350 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
87 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 4517.54
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 4517.5402
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
87 can be fit into 260 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 4517.54022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 4517.54022 with a balance of 8.6e-05.
