Let's divide 292215 by 21
Let's see how many times 21 fits into 292215.

Moving on to step 1:
21 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
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

Step 2:
21 can be fit into 29 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 21 from 29 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 21

Moving on to step 3:
82 divided by 21 is 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 63 from 82 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 21

On to step 4:
21 can be fit into 192 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 189 from 192 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 21

Moving on to step 5:
31 divided by 21 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1391.0
Deduct 21 from 31 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 21

Let's proceed to step 6:
105 divided by 21 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13915.0
Subtracting 105 from 105 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.

Moving on to step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13915.0
If we subtract 0 from 0, we 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.

Step 8:
If we divide 0 by 21, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13915.0
Deduct 0 from 0 and we're left 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 13915.0 and a remainder of 0.0.
