18397040 ÷ 497 
Let's see how many times 497 fits into 18397040.

Going ahead to step 1:
1 divided by 497 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 497

Advancing to step 2:
When dividing 18 by 497, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 497

On to step 3:
The number 497 fits into 183 0 times, leaving a remainder of 183.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Take the next digit (9) from the dividend and append it to 183, then repeat: 1839 / 497

Advancing to step 4:
If we divide 1839 by 497, we get 3 and a remainder of 348.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1491 from 1839 to get 348.
Bring next digit (7) of the dividend behind the 348 and repeat the process: 3487 / 497

Step 5:
When dividing 3487 by 497, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 8 after subtracting 3479 from 3487.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 497

Let's proceed to step 6:
If we divide 80 by 497, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
If we subtract 0 from 80, we get 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 497

Moving on to step 7:
If we divide 804 by 497, we get 1 and a remainder of 307.
The number 1 becomes the next digit in our result. 
Result so far: 3701.0
Subtracting 497 from 804 leaves us with 307.
Bring next digit (0) of the dividend behind the 307 and repeat the process: 3070 / 497

Going ahead to step 8:
497 can be fit into 3070 6 times, resulting in a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 37016.0
The remainder is 88 after subtracting 2982 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
880 divided by 497 is 1 with a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 37016.1
Subtract 497 from 880 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 10:
When dividing 3830 by 497, we get 7 with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 37016.17
Subtracting 3479 from 3830 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 11:
When dividing 3510 by 497, we get 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 37016.177
The remainder is 31 after subtracting 3479 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 37016.177 with a remaining 0.0031.
