428580 ÷ 16 
We're looking to find how many times 16 goes into 428580.

Step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 16

Moving on to step 2:
42 divided by 16 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 32 from 42 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 16

On to step 3:
When dividing 108 by 16, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 96 from 108 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 16

Going ahead to step 4:
16 can be fit into 125 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 267.0
If we subtract 112 from 125, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 16

Going ahead to step 5:
When dividing 138 by 16, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 2678.0
If we take 128 away from 138, we end up with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 16

Step 6:
If we divide 100 by 16, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 26786.0
If we take 96 away from 100, we end up 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.

Moving on to step 7:
When dividing 40 by 16, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 26786.2
Subtracting 32 from 40 leaves us 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.

Going ahead to step 8:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 26786.25
Subtracting 80 from 80 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 9:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26786.25
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.

Let's proceed to step 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26786.25
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.

Our division results in 26786.25 with a remaining 0.0.
