We divide 215191 by 16
Let's see how many times 16 fits into 215191.

Going ahead to step 1:
If we divide 2 by 16, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 16

Moving on to step 2:
The number 16 fits into 21 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 5 after subtracting 16 from 21.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 16

Going ahead to step 3:
16 goes into 55 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 48 from 55, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 16

Let's proceed to step 4:
The number 16 fits into 71 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 134.0
If we subtract 64 from 71, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 16

Going ahead to step 5:
When dividing 79 by 16, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 1344.0
Deduct 64 from 79 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 16

Moving on to step 6:
16 goes into 151 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 13449.0
Deduct 144 from 151 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 16 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 13449.4
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
16 goes into 60 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13449.43
Subtract 48 from 60 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 13449.437
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 13449.4375
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13449.4375
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.

Moving on to step 12:
16 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: 13449.4375
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.

The quotient of the division is 13449.4375, and the remainder is 0.0.
