18690236 ÷ 523 
We want to figure out the number of times 18690236 can be divided by 523.

Going ahead to step 1:
523 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 523

Advancing to step 2:
523 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 523

Moving on to step 3:
523 goes into 186 0 times with a remainder of 186.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Take the next digit (9) from the dividend and append it to 186, then repeat: 1869 / 523

Advancing to step 4:
1869 divided by 523 is 3 with a remainder of 300.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1569 from 1869 to get 300.
Include the next digit (0) from the dividend after 300, then repeat: 3000 / 523

Step 5:
The number 523 fits into 3000 5 times, leaving a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 385 after subtracting 2615 from 3000.
Include the next digit (2) from the dividend after 385, then repeat: 3852 / 523

On to step 6:
523 can be fit into 3852 7 times, resulting in a remainder of 191.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
Subtracting 3661 from 3852 leaves us with 191.
Append the next digit (3) from the dividend to 191 and continue with: 1913 / 523

Going ahead to step 7:
The number 523 fits into 1913 3 times, leaving a remainder of 344.
The number 3 becomes the next digit in our result. 
Result so far: 3573.0
The remainder is 344 after subtracting 1569 from 1913.
Bring next digit (6) of the dividend behind the 344 and repeat the process: 3446 / 523

On to step 8:
3446 divided by 523 is 6 with a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 35736.0
Deduct 3138 from 3446 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 9:
The number 523 fits into 3080 5 times, leaving a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 35736.5
If we subtract 2615 from 3080, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 10:
523 can be fit into 4650 8 times, resulting in a remainder of 466.
The next digit of our result is 8. 
Result so far: 35736.58
If we take 4184 away from 4650, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 11:
523 goes into 4660 8 times with a remainder of 476.
The next digit of our result is 8. 
Result so far: 35736.588
Subtracting 4184 from 4660 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

In conclusion, the division gives 35736.588 with a balance of 0.0476.
