We're dividing 216961 by 15 
Let's see how many times 15 fits into 216961.

Step 1:
15 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 15

Advancing to 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
The remainder is 6 after subtracting 15 from 21.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 15

Advancing to step 3:
If we divide 66 by 15, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 60 from 66 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 15

Advancing to step 4:
15 can be fit into 69 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 60 from 69 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 15

Let's proceed to step 5:
15 goes into 96 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 1446.0
Subtracting 90 from 96 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 15

On to step 6:
61 divided by 15 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 14464.0
If we subtract 60 from 61, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 15 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14464.0
If we take 0 away from 10, we end up 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.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 14464.06
Subtract 90 from 100 to 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 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 14464.066
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.

The quotient of the division is 14464.066, and the remainder is 0.001.
