We're dividing 304639 by 87 
We want to figure out the number of times 304639 can be divided by 87.

Advancing to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 87

Moving on to step 2:
When dividing 30 by 87, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 87

Advancing to step 3:
If we divide 304 by 87, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 261 from 304 leaves us with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 87

Step 4:
The number 87 fits into 436 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 35.0
If we take 435 away from 436, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 87

Let's proceed to step 5:
The number 87 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 350.0
If we subtract 0 from 13, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 87

Let's proceed to step 6:
When dividing 139 by 87, we get 1 with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 3501.0
If we take 87 away from 139, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
The number 87 fits into 520 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 3501.5
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
87 can be fit into 850 9 times, resulting in a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 3501.59
Subtracting 783 from 850 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
The number 87 fits into 670 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 3501.597
Deduct 609 from 670 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
When dividing 610 by 87, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3501.5977
If we take 609 away from 610, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 3501.5977 and a remainder of 1e-05.
