19194455 ÷ 457 
Let's see how many times 457 fits into 19194455.

Going ahead to step 1:
1 divided by 457 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 457

On to step 2:
457 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 457

Advancing to step 3:
457 goes into 191 0 times with a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 191 to get 191.
Grab the next digit (9) from the dividend, add it to 191, then carry on: 1919 / 457

Advancing to step 4:
457 goes into 1919 4 times with a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1828 from 1919 leaves us with 91.
Include the next digit (4) from the dividend after 91, then repeat: 914 / 457

On to step 5:
457 goes into 914 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 914 from 914 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 457

On to step 6:
The number 457 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 420.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 457

Advancing to step 7:
The number 457 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 4200.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 457

Let's proceed to step 8:
457 can be fit into 455 0 times, resulting in a remainder of 455.
Use 0 as the next digit of our solution. 
Result so far: 42000.0
Subtract 0 from 455 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 9:
457 can be fit into 4550 9 times, resulting in a remainder of 437.
Use 9 as the next digit of our solution. 
Result so far: 42000.9
If we subtract 4113 from 4550, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 10:
457 can be fit into 4370 9 times, resulting in a remainder of 257.
Write down 9 as next digit of the result. 
Result so far: 42000.99
Deduct 4113 from 4370 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

The quotient of the division is 42000.99, and the remainder is 0.257.
