We divide 473521 by 90
We want to divide 473521 by 90.

Going ahead to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 90

Step 2:
90 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 90

Advancing to step 3:
If we divide 473 by 90, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 450 from 473, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 90

Going ahead to step 4:
90 can be fit into 235 2 times, resulting in a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 180 from 235 leaves us with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 90

Moving on to step 5:
The number 90 fits into 552 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 526.0
Subtracting 540 from 552 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 90

Moving on to step 6:
The number 90 fits into 121 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 5261.0
Subtracting 90 from 121 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
90 goes into 310 3 times with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 5261.3
Subtract 270 from 310 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.

Advancing to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 5261.34
Subtracting 360 from 400 leaves us 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.

Moving on to step 9:
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: 5261.344
The remainder is 40 after subtracting 360 from 400.
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 result is 5261.344 with a remainder of 0.004.
