We're dividing 904918 by 90 
We're looking to find how many times 90 goes into 904918.

Going ahead to step 1:
When dividing 9 by 90, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 90

Let's proceed to step 2:
90 divided by 90 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 90 from 90.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 90

Going ahead to step 3:
When dividing 4 by 90, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 90

Moving on to step 4:
90 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 90

Going ahead to step 5:
90 goes into 491 5 times with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 1005.0
Subtract 450 from 491 to get 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 90

Step 6:
The number 90 fits into 418 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 10054.0
Deduct 360 from 418 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
580 divided by 90 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 10054.6
Subtract 540 from 580 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 10054.64
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 90 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 10054.644
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10054.644, with a leftover of 0.004.
