18909513 ÷ 217 
We want to figure out the number of times 18909513 can be divided by 217.

On to step 1:
If we divide 1 by 217, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 217

Step 2:
If we divide 18 by 217, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 217

Let's proceed to step 3:
If we divide 189 by 217, we get 0 and a remainder of 189.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Take the next digit (0) from the dividend and append it to 189, then repeat: 1890 / 217

Moving on to step 4:
When dividing 1890 by 217, we get 8 with a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 1736 away from 1890, we end up with 154.
Append the next digit (9) from the dividend to 154 and continue with: 1549 / 217

Advancing to step 5:
If we divide 1549 by 217, we get 7 and a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 1519 from 1549 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 217

Advancing to step 6:
305 divided by 217 is 1 with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 871.0
Deduct 217 from 305 and we're left with 88.
Bring next digit (1) of the dividend behind the 88 and repeat the process: 881 / 217

Advancing to step 7:
217 goes into 881 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 8714.0
If we take 868 away from 881, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 217

Going ahead to step 8:
If we divide 133 by 217, we get 0 and a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 87140.0
Subtract 0 from 133 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
217 can be fit into 1330 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 87140.6
If we take 1302 away from 1330, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
217 goes into 280 1 times with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 87140.61
Deduct 217 from 280 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
217 can be fit into 630 2 times, resulting in a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 87140.612
If we subtract 434 from 630, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
When dividing 1960 by 217, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 87140.6129
The remainder is 7 after subtracting 1953 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
If we divide 70 by 217, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 87140.6129
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
700 divided by 217 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 87140.612903
Subtract 651 from 700 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 15:
217 can be fit into 490 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 87140.6129032
The remainder is 56 after subtracting 434 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
560 divided by 217 is 2 with a remainder of 126.
The next digit of our result is 2. 
Result so far: 87140.61290322
The remainder is 126 after subtracting 434 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

After the division, we end up with 87140.61290322 and a remainder of 1.26e-07.
