We divide 215397 by 16
We're looking to find how many times 16 goes into 215397.

Going ahead to step 1:
16 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 16

On to step 2:
If we divide 21 by 16, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 16 away from 21, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 16

Let's proceed to step 3:
If we divide 55 by 16, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 48 from 55 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 16

Advancing to step 4:
16 goes into 73 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 64 from 73 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 16

On to step 5:
When dividing 99 by 16, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 1346.0
Subtracting 96 from 99 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 16

On to step 6:
If we divide 37 by 16, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 13462.0
Deduct 32 from 37 and we're left 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.

Let's proceed to step 7:
When dividing 50 by 16, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 13462.3
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
16 can be fit into 20 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 13462.31
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 13462.312
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 13462.3125
If we take 80 away from 80, 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.

Let's proceed to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13462.3125
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.

Moving on to step 12:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13462.3125
Subtract 0 from 0 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.

The quotient of the division is 13462.3125, and the remainder is 0.0.
