451020 ÷ 16 
We want to figure out the number of times 451020 can be divided by 16.

Let's proceed to step 1:
4 divided by 16 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 16

Going ahead to step 2:
45 divided by 16 is 2 with 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.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 16

On to step 3:
When dividing 131 by 16, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 128 from 131 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 16

Advancing to step 4:
The number 16 fits into 30 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 281.0
If we subtract 16 from 30, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 16

On to step 5:
142 divided by 16 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 2818.0
If we take 128 away from 142, we end up with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 16

On to step 6:
16 goes into 140 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 28188.0
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 7:
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: 28188.7
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.

Moving on to step 8:
80 divided by 16 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 28188.75
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.

Going ahead to step 9:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 28188.75
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.

Advancing to step 10:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28188.75
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 28188.75 and a remainder of 0.0.
