221649 divided by 15 
We want to divide 221649 by 15.

Step 1:
15 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 15

Let's proceed to step 2:
When dividing 22 by 15, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 15 from 22 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 15

Advancing to step 3:
71 divided by 15 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 60 from 71 to get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 15

Advancing to step 4:
116 divided by 15 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 105 from 116 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 15

On to step 5:
15 can be fit into 114 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1477.0
Subtract 105 from 114 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Advancing to step 6:
15 can be fit into 99 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 14776.0
Subtract 90 from 99 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 15, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 14776.6
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14776.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14776.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 14776.6 and a remainder of 0.0.
