216212 divided by 15 
We want to divide 216212 by 15.

Step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 15

On to step 2:
The number 15 fits into 21 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 15 from 21 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Advancing to step 3:
When dividing 66 by 15, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 60 from 66 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 15

Going ahead to step 4:
The number 15 fits into 62 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Deduct 60 from 62 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 15

Going ahead to step 5:
15 can be fit into 21 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1441.0
Subtracting 15 from 21 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 15

Step 6:
62 divided by 15 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 14414.0
If we subtract 60 from 62, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 15, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 14414.1
If we subtract 15 from 20, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 14414.13
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 14414.133
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 14414.133, with a leftover of 0.0005.
