Let's divide 304912 by 87
Our goal is to divide 304912 by 87.

On to step 1:
87 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 87

Advancing to step 2:
The number 87 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 87

Advancing to step 3:
87 goes into 304 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 261 from 304 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 87

On to step 4:
If we divide 439 by 87, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 435 away from 439, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 87

Going ahead to step 5:
87 goes into 41 0 times with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 350.0
Subtracting 0 from 41 leaves us with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 87

On to step 6:
When dividing 412 by 87, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 3504.0
Subtract 348 from 412 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
640 divided by 87 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 3504.7
Deduct 609 from 640 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
87 can be fit into 310 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 3504.73
If we take 261 away from 310, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
When dividing 490 by 87, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 3504.735
The remainder is 55 after subtracting 435 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
550 divided by 87 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 3504.7356
If we subtract 522 from 550, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 87, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3504.73563
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
The number 87 fits into 190 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 3504.735632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 87, we get 1 and a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 3504.7356321
Subtracting 87 from 160 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
If we divide 730 by 87, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 3504.73563218
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 3504.73563218 and a remainder of 3.4e-08.
