We look at the division of 19934080 by 16 
We want to figure out the number of times 19934080 can be divided by 16.

On to step 1:
1 divided by 16 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 16

Advancing to step 2:
16 can be fit into 19 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 16 from 19.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 16

Advancing to step 3:
39 divided by 16 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 32 from 39 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 16

Moving on to step 4:
If we divide 73 by 16, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 64 away from 73, we end up with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 16

On to step 5:
If we divide 94 by 16, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 1245.0
Subtract 80 from 94 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 16

On to step 6:
When dividing 140 by 16, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 12458.0
Deduct 128 from 140 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 16

Let's proceed to step 7:
If we divide 128 by 16, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 124588.0
If we subtract 128 from 128, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 16

Advancing to step 8:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1245880.0
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.

Moving on to step 9:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1245880.0
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.

Step 10:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1245880.0
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.

Our division results in 1245880.0 with a remaining 0.0.
