553062 ÷ 90 
We want to figure out the number of times 553062 can be divided by 90.

Step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 90

Step 2:
If we divide 55 by 90, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 90

Moving on to step 3:
553 divided by 90 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 540 from 553 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 90

Moving on to step 4:
The number 90 fits into 130 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 40 after subtracting 90 from 130.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 90

On to step 5:
90 can be fit into 406 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 614.0
If we take 360 away from 406, we end up with 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 90

Advancing to step 6:
90 can be fit into 462 5 times, resulting in a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 6145.0
The remainder is 12 after subtracting 450 from 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 90, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 6145.1
Subtracting 90 from 120 leaves us 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.

Advancing to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 6145.13
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.

On to step 9:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 6145.133
If we subtract 270 from 300, 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.

The final result is 6145.133 with a remainder of 0.003.
