Let's divide 841485 by 90
We want to figure out the number of times 841485 can be divided by 90.

Step 1:
If we divide 8 by 90, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 90

Moving on to step 2:
90 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 90

Going ahead to step 3:
The number 90 fits into 841 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 810 from 841 to get 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 90

Step 4:
If we divide 314 by 90, we get 3 and a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 270 from 314 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 90

Moving on to step 5:
If we divide 448 by 90, we get 4 and a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 934.0
If we subtract 360 from 448, we get 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 90

Let's proceed to step 6:
The number 90 fits into 885 9 times, leaving a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 9349.0
If we take 810 away from 885, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
90 can be fit into 750 8 times, resulting in a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 9349.8
If we subtract 720 from 750, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 90 is 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 9349.83
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
300 divided by 90 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 9349.833
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 9349.833 and a remainder of 0.003.
