393236 divided by 87 
Let's see how many times 87 fits into 393236.

On to step 1:
87 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 87

Moving on to step 2:
If we divide 39 by 87, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 87

Moving on to step 3:
87 goes into 393 4 times with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 348 from 393, we get 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 87

Let's proceed to step 4:
If we divide 452 by 87, we get 5 and a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 435 from 452 and we're left with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 87

Going ahead to step 5:
When dividing 173 by 87, we get 1 with a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 451.0
The remainder is 86 after subtracting 87 from 173.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 87

On to step 6:
87 can be fit into 866 9 times, resulting in a remainder of 83.
The next digit of our result is 9. 
Result so far: 4519.0
If we take 783 away from 866, we end up 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 7:
If we divide 830 by 87, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 4519.9
The remainder is 47 after subtracting 783 from 830.
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 8:
The number 87 fits into 470 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4519.95
Deduct 435 from 470 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
If we divide 350 by 87, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 4519.954
If we subtract 348 from 350, we 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.

Let's proceed to step 10:
20 divided by 87 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4519.954
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 4519.95402
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.

Advancing to step 12:
87 goes into 260 2 times with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 4519.954022
Subtracting 174 from 260 leaves us 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.

After the division, we end up with 4519.954022 and a remainder of 8.6e-06.
