We divide 918393 by 90
Let's see how many times 90 fits into 918393.

Going ahead to step 1:
90 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 90

Going ahead to step 2:
The number 90 fits into 91 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 90 from 91 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 90

Let's proceed to step 3:
90 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
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

On to step 4:
90 can be fit into 183 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 180 from 183 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 90

Moving on to step 5:
90 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 90

Step 6:
90 goes into 393 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 10204.0
Subtract 360 from 393 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
When dividing 330 by 90, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 10204.3
The remainder is 60 after subtracting 270 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
90 goes into 600 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10204.36
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
90 goes into 600 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10204.366
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 10204.366 with a balance of 0.006.
