19029134 ÷ 80 
We want to figure out the number of times 19029134 can be divided by 80.

Let's proceed to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 80

Let's proceed to step 2:
80 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 80

Advancing to step 3:
If we divide 190 by 80, we get 2 and a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 160 away from 190, we end up with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 80

Let's proceed to step 4:
80 goes into 302 3 times with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 240 from 302 to get 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 80

Moving on to step 5:
80 can be fit into 629 7 times, resulting in a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 237.0
If we take 560 away from 629, we end up with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 80

Going ahead to step 6:
If we divide 691 by 80, we get 8 and a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 2378.0
If we take 640 away from 691, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 80

Going ahead to step 7:
The number 80 fits into 513 6 times, leaving a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 23786.0
The remainder is 33 after subtracting 480 from 513.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 80

Advancing to step 8:
The number 80 fits into 334 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 237864.0
If we take 320 away from 334, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
When dividing 140 by 80, we get 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 237864.1
Subtract 80 from 140 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 237864.17
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 237864.175
Subtract 400 from 400 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 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 237864.175
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 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 237864.175
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 final outcome is 237864.175, with a leftover of 0.0.
