We're dividing 1681784 by 515 
Our goal is to divide 1681784 by 515.

Advancing to step 1:
1 divided by 515 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 515

Step 2:
515 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 515

On to step 3:
The number 515 fits into 168 0 times, leaving a remainder of 168.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Include the next digit (1) from the dividend after 168, then repeat: 1681 / 515

Going ahead to step 4:
515 goes into 1681 3 times with a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1545 away from 1681, we end up with 136.
Take the next digit (7) from the dividend and append it to 136, then repeat: 1367 / 515

Advancing to step 5:
515 can be fit into 1367 2 times, resulting in a remainder of 337.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 1030 from 1367 and we're left with 337.
Grab the next digit (8) from the dividend, add it to 337, then carry on: 3378 / 515

On to step 6:
515 can be fit into 3378 6 times, resulting in a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 326.0
If we take 3090 away from 3378, we end up with 288.
Take the next digit (4) from the dividend and append it to 288, then repeat: 2884 / 515

Going ahead to step 7:
515 goes into 2884 5 times with a remainder of 309.
Write down 5 as next digit of the result. 
Result so far: 3265.0
If we take 2575 away from 2884, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 8:
515 can be fit into 3090 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 3265.6
If we take 3090 away from 3090, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 515 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3265.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
515 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3265.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3265.6 and a remainder of 0.0.
