We're dividing 642130 by 16 
Let's see how many times 16 fits into 642130.

Going ahead to step 1:
If we divide 6 by 16, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 16

Advancing to step 2:
The number 16 fits into 64 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 64 away from 64, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 16

Advancing to step 3:
2 divided by 16 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 16

Step 4:
The number 16 fits into 21 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 401.0
Subtract 16 from 21 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 16

Let's proceed to step 5:
The number 16 fits into 53 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 4013.0
The remainder is 5 after subtracting 48 from 53.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 16

Step 6:
When dividing 50 by 16, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 40133.0
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 16, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 40133.1
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 16 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 40133.12
Deduct 32 from 40 and we're left 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 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 40133.125
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 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40133.125
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40133.125
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.

Our division results in 40133.125 with a remaining 0.0.
