17050209 ÷ 312 
Let's see how many times 312 fits into 17050209.

Moving on to step 1:
1 divided by 312 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 312

Going ahead to step 2:
312 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 312

Advancing to step 3:
If we divide 170 by 312, we get 0 and a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 170, we end up with 170.
Bring next digit (5) of the dividend behind the 170 and repeat the process: 1705 / 312

Moving on to step 4:
1705 divided by 312 is 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 1560 from 1705 leaves us with 145.
Take the next digit (0) from the dividend and append it to 145, then repeat: 1450 / 312

Moving on to step 5:
312 can be fit into 1450 4 times, resulting in a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 1248 from 1450, we get 202.
Grab the next digit (2) from the dividend, add it to 202, then carry on: 2022 / 312

Moving on to step 6:
2022 divided by 312 is 6 with a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 546.0
Deduct 1872 from 2022 and we're left with 150.
Include the next digit (0) from the dividend after 150, then repeat: 1500 / 312

Step 7:
When dividing 1500 by 312, we get 4 with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 5464.0
Subtracting 1248 from 1500 leaves us with 252.
Append the next digit (9) from the dividend to 252 and continue with: 2529 / 312

Step 8:
If we divide 2529 by 312, we get 8 and a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 54648.0
Subtract 2496 from 2529 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
312 goes into 330 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 54648.1
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
312 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 54648.1
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
The number 312 fits into 1800 5 times, leaving a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 54648.105
Deduct 1560 from 1800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
312 can be fit into 2400 7 times, resulting in a remainder of 216.
Record the quotient 7 as the next digit in the result. 
Result so far: 54648.1057
The remainder is 216 after subtracting 2184 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 13:
When dividing 2160 by 312, we get 6 with a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 54648.10576
Subtract 1872 from 2160 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 14:
312 can be fit into 2880 9 times, resulting in a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 54648.105769
Subtract 2808 from 2880 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
When dividing 720 by 312, we get 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 54648.1057692
Subtract 624 from 720 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
312 can be fit into 960 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 54648.10576923
Subtract 936 from 960 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 54648.10576923 and a remainder of 2.4e-08.
