18310992 ÷ 808 
We want to divide 18310992 by 808.

Going ahead to step 1:
When dividing 1 by 808, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 808

Advancing to step 2:
18 divided by 808 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 808

Going ahead to step 3:
When dividing 183 by 808, we get 0 with a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Append the next digit (1) from the dividend to 183 and continue with: 1831 / 808

Going ahead to step 4:
When dividing 1831 by 808, we get 2 with a remainder of 215.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 215 after subtracting 1616 from 1831.
Bring next digit (0) of the dividend behind the 215 and repeat the process: 2150 / 808

Going ahead to step 5:
The number 808 fits into 2150 2 times, leaving a remainder of 534.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1616 from 2150 to get 534.
Take the next digit (9) from the dividend and append it to 534, then repeat: 5349 / 808

Advancing to step 6:
808 can be fit into 5349 6 times, resulting in a remainder of 501.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
Subtracting 4848 from 5349 leaves us with 501.
Fetch the next digit (9) from the dividend, attach it to 501 and continue: 5019 / 808

Moving on to step 7:
If we divide 5019 by 808, we get 6 and a remainder of 171.
The next digit of our result is 6. 
Result so far: 2266.0
If we take 4848 away from 5019, we end up with 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 808

Let's proceed to step 8:
1712 divided by 808 is 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 22662.0
If we subtract 1616 from 1712, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 808 fits into 960 1 times, leaving a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 22662.1
Deduct 808 from 960 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
When dividing 1520 by 808, we get 1 with a remainder of 712.
The next digit of our result is 1. 
Result so far: 22662.11
Deduct 808 from 1520 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

In conclusion, the division gives 22662.11 with a balance of 0.712.
