18863568 ÷ 611 
Our goal is to divide 18863568 by 611.

Going ahead to step 1:
1 divided by 611 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 611

On to step 2:
611 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 611

Advancing to step 3:
188 divided by 611 is 0 with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Append the next digit (6) from the dividend to 188 and continue with: 1886 / 611

Advancing to step 4:
611 goes into 1886 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1833 from 1886 leaves us with 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 611

Advancing to step 5:
611 goes into 533 0 times with a remainder of 533.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 533 after subtracting 0 from 533.
Fetch the next digit (5) from the dividend, attach it to 533 and continue: 5335 / 611

Let's proceed to step 6:
5335 divided by 611 is 8 with a remainder of 447.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
If we subtract 4888 from 5335, we get 447.
Append the next digit (6) from the dividend to 447 and continue with: 4476 / 611

Going ahead to step 7:
4476 divided by 611 is 7 with a remainder of 199.
The next digit of our result is 7. 
Result so far: 3087.0
Deduct 4277 from 4476 and we're left with 199.
Bring next digit (8) of the dividend behind the 199 and repeat the process: 1998 / 611

Let's proceed to step 8:
If we divide 1998 by 611, we get 3 and a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 30873.0
Deduct 1833 from 1998 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
When dividing 1650 by 611, we get 2 with a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 30873.2
If we subtract 1222 from 1650, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 10:
When dividing 4280 by 611, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 30873.27
Subtracting 4277 from 4280 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
611 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 30873.27
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
611 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 30873.27
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 30873.27, and the remainder is 0.003.
