Moving on to step 2:
When dividing 11 by 619, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 619

On to step 3:
619 can be fit into 119 0 times, resulting in a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 119, we get 119.
Grab the next digit (8) from the dividend, add it to 119, then carry on: 1198 / 619

Step 4:
619 can be fit into 1198 1 times, resulting in a remainder of 579.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 619 from 1198 leaves us with 579.
Include the next digit (8) from the dividend after 579, then repeat: 5798 / 619

Moving on to step 5:
The number 619 fits into 5798 9 times, leaving a remainder of 227.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 5571 from 5798 and we're left with 227.
Take the next digit (9) from the dividend and append it to 227, then repeat: 2279 / 619

Moving on to step 6:
2279 divided by 619 is 3 with a remainder of 422.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 1857 from 2279 leaves us with 422.
Include the next digit (6) from the dividend after 422, then repeat: 4226 / 619

Moving on to step 7:
4226 divided by 619 is 6 with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 1936.0
Subtracting 3714 from 4226 leaves us with 512.
Take the next digit (0) from the dividend and append it to 512, then repeat: 5120 / 619

Going ahead to step 8:
When dividing 5120 by 619, we get 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 19368.0
The remainder is 168 after subtracting 4952 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
The number 619 fits into 1680 2 times, leaving a remainder of 442.
Write down 2 as next digit of the result. 
Result so far: 19368.2
If we subtract 1238 from 1680, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
619 goes into 4420 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 19368.27
The remainder is 87 after subtracting 4333 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 11:
619 goes into 870 1 times with a remainder of 251.
The next digit of our result is 1. 
Result so far: 19368.271
If we subtract 619 from 870, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 12:
When dividing 2510 by 619, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 19368.2714
If we take 2476 away from 2510, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
340 divided by 619 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 19368.2714
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
If we divide 3400 by 619, we get 5 and a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 19368.271405
If we take 3095 away from 3400, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 15:
619 can be fit into 3050 4 times, resulting in a remainder of 574.
Use 4 as the next digit of our solution. 
Result so far: 19368.2714054
If we subtract 2476 from 3050, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 16:
The number 619 fits into 5740 9 times, leaving a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 19368.27140549
Deduct 5571 from 5740 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Our division results in 19368.27140549 with a remaining 1.69e-07.
