18318932 divided by 90 
Our goal is to divide 18318932 by 90.

Going ahead to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 90

Advancing to step 2:
18 divided by 90 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 90

Advancing to step 3:
183 divided by 90 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 180 away from 183, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 90

Moving on to step 4:
90 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 31 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 90

Let's proceed to step 5:
318 divided by 90 is 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 270 away from 318, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 90

Step 6:
489 divided by 90 is 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 2035.0
If we take 450 away from 489, we end up with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 90

Step 7:
393 divided by 90 is 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 20354.0
Subtract 360 from 393 to get 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 90

On to step 8:
The number 90 fits into 332 3 times, leaving a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 203543.0
If we subtract 270 from 332, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
The number 90 fits into 620 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 203543.6
The remainder is 80 after subtracting 540 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
If we divide 800 by 90, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 203543.68
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
90 goes into 800 8 times with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 203543.688
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 203543.688, with a leftover of 0.008.
