19896940 ÷ 16 
We want to figure out the number of times 19896940 can be divided by 16.

Advancing to step 1:
16 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 16

Step 2:
When dividing 19 by 16, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 16 from 19.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 16

Moving on to step 3:
When dividing 38 by 16, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 32 from 38 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 16

Moving on to step 4:
16 can be fit into 69 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 64 from 69 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

Let's proceed to step 5:
16 goes into 56 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 1243.0
Subtracting 48 from 56 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 16

Advancing to step 6:
When dividing 89 by 16, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 12435.0
Subtract 80 from 89 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 16

Let's proceed to step 7:
94 divided by 16 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 124355.0
Deduct 80 from 94 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 16

Step 8:
When dividing 140 by 16, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1243558.0
Subtract 128 from 140 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1243558.7
Subtract 112 from 120 to 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.

Going ahead to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1243558.75
If we take 80 away from 80, 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.

Step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1243558.75
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.

Let's proceed to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1243558.75
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.

In conclusion, the division gives 1243558.75 with a balance of 0.0.
