Let's divide 478046 by 90
We're looking to find how many times 90 goes into 478046.

Moving on to step 1:
4 divided by 90 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 90

Moving on to step 2:
90 can be fit into 47 0 times, resulting in a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 90

Let's proceed to step 3:
When dividing 478 by 90, we get 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 450 from 478 leaves us with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 90

On to step 4:
The number 90 fits into 280 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 270 from 280 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 90

Going ahead to step 5:
When dividing 104 by 90, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 531.0
The remainder is 14 after subtracting 90 from 104.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 90

On to step 6:
90 can be fit into 146 1 times, resulting in a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 5311.0
Subtract 90 from 146 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
When dividing 560 by 90, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5311.6
Subtracting 540 from 560 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 5311.62
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 5311.622
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 5311.622 and a remainder of 0.002.
