We divide 217240 by 15
We're looking to find how many times 15 goes into 217240.

On to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

Step 2:
15 goes into 21 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 15 away from 21, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 15

Advancing to step 3:
15 can be fit into 67 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 60 from 67 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 15

Going ahead to step 4:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Deduct 60 from 72 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

Step 5:
The number 15 fits into 124 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1448.0
Deduct 120 from 124 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 15

Step 6:
When dividing 40 by 15, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 14482.0
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 14482.6
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 14482.66
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 14482.66, with a leftover of 0.01.
