We're dividing 451315 by 16 
We want to divide 451315 by 16.

On to step 1:
4 divided by 16 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 16

Moving on to step 2:
The number 16 fits into 45 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 32 from 45 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 16

Let's proceed to step 3:
If we divide 131 by 16, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 128 from 131, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 16

Going ahead to step 4:
The number 16 fits into 33 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 282.0
If we subtract 32 from 33, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 16

Going ahead to step 5:
11 divided by 16 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 2820.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 16

On to step 6:
16 goes into 115 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 28207.0
If we subtract 112 from 115, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 16, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 28207.1
If we subtract 16 from 30, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 16, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 28207.18
Deduct 128 from 140 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
16 goes into 120 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 28207.187
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:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28207.1875
Subtract 80 from 80 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.

On to step 11:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28207.1875
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 12:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28207.1875
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 final result is 28207.1875 with a remainder of 0.0.
