We're dividing 420428 by 16 
We want to divide 420428 by 16.

Going ahead to step 1:
If we divide 4 by 16, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 16

Let's proceed to step 2:
When dividing 42 by 16, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 32 from 42 leaves us with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 16

Advancing to step 3:
100 divided by 16 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 96 from 100, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 16

Let's proceed to step 4:
44 divided by 16 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
Subtracting 32 from 44 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 16

Step 5:
16 goes into 122 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 2627.0
The remainder is 10 after subtracting 112 from 122.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 16

Going ahead to step 6:
If we divide 108 by 16, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 26276.0
The remainder is 12 after subtracting 96 from 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 26276.7
Subtracting 112 from 120 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.

Moving on to step 8:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 26276.75
If we subtract 80 from 80, 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.

Step 9:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26276.75
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.

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: 26276.75
The remainder is 0 after subtracting 0 from 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 26276.75 with a remainder of 0.0.
