Let's divide 801492 by 90
We're looking to find how many times 90 goes into 801492.

Going ahead to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 90

Moving on to step 2:
If we divide 80 by 90, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 90

Step 3:
90 can be fit into 801 8 times, resulting in a remainder of 81.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 720 from 801 to get 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 90

Advancing to step 4:
814 divided by 90 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 89.0
Deduct 810 from 814 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 90

On to step 5:
90 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 890.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 90

Moving on to step 6:
492 divided by 90 is 5 with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 8905.0
Deduct 450 from 492 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
If we divide 420 by 90, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 8905.4
Subtract 360 from 420 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.

Let's proceed to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 8905.46
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.

Step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 8905.466
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 8905.466, with a leftover of 0.006.
