16455045 ÷ 19 
We're looking to find how many times 19 goes into 16455045.

On to step 1:
The number 19 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 19

Advancing to step 2:
When dividing 16 by 19, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 19

Let's proceed to step 3:
19 can be fit into 164 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 152 from 164 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 19

Going ahead to step 4:
When dividing 125 by 19, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 114 away from 125, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 19

Moving on to step 5:
19 can be fit into 115 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 866.0
Subtract 114 from 115 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 19

Step 6:
If we divide 10 by 19, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8660.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 19

Moving on to step 7:
The number 19 fits into 104 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 86605.0
Deduct 95 from 104 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 19

On to step 8:
19 can be fit into 95 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 866055.0
If we subtract 95 from 95, 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.

Moving on to step 9:
When dividing 0 by 19, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 866055.0
Subtracting 0 from 0 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.

Advancing to step 10:
When dividing 0 by 19, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 866055.0
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 866055.0 with a remaining 0.0.
