45087 ÷ 19 
We want to figure out the number of times 45087 can be divided by 19.

On to step 1:
The number 19 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 19

Let's proceed to step 2:
19 goes into 45 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 7 after subtracting 38 from 45.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 19

Advancing to step 3:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 13 after subtracting 57 from 70.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 19

Advancing to step 4:
19 can be fit into 138 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 237.0
If we take 133 away from 138, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 19

On to step 5:
19 goes into 57 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2373.0
If we subtract 57 from 57, 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 6:
When dividing 0 by 19, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2373.0
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.

On to step 7:
19 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2373.0
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.

The quotient of the division is 2373.0, and the remainder is 0.0.
