18061288 ÷ 491 
Our goal is to divide 18061288 by 491.

Step 1:
If we divide 1 by 491, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 491

Advancing to step 2:
The number 491 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 491

On to step 3:
180 divided by 491 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Include the next digit (6) from the dividend after 180, then repeat: 1806 / 491

Moving on to step 4:
1806 divided by 491 is 3 with a remainder of 333.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1473 from 1806 and we're left with 333.
Append the next digit (1) from the dividend to 333 and continue with: 3331 / 491

Let's proceed to step 5:
491 goes into 3331 6 times with a remainder of 385.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 2946 away from 3331, we end up with 385.
Include the next digit (2) from the dividend after 385, then repeat: 3852 / 491

Step 6:
491 can be fit into 3852 7 times, resulting in a remainder of 415.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
If we take 3437 away from 3852, we end up with 415.
Include the next digit (8) from the dividend after 415, then repeat: 4158 / 491

Moving on to step 7:
4158 divided by 491 is 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 3678.0
If we take 3928 away from 4158, we end up with 230.
Take the next digit (8) from the dividend and append it to 230, then repeat: 2308 / 491

Advancing to step 8:
The number 491 fits into 2308 4 times, leaving a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 36784.0
If we take 1964 away from 2308, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 9:
If we divide 3440 by 491, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 36784.7
Subtract 3437 from 3440 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
491 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 36784.7
If we take 0 away from 30, we end up 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.

Step 11:
The number 491 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 36784.7
Subtract 0 from 300 to get 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 final outcome is 36784.7, with a leftover of 0.03.
