Let's divide 580550 by 90
We want to divide 580550 by 90.

Moving on to step 1:
90 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 90

Going ahead to step 2:
90 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 90

Let's proceed to step 3:
The number 90 fits into 580 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 40 after subtracting 540 from 580.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 90

Let's proceed to step 4:
405 divided by 90 is 4 with a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 360 from 405 to get 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 90

Going ahead to step 5:
90 can be fit into 455 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 645.0
If we take 450 away from 455, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 90

Let's proceed to step 6:
When dividing 50 by 90, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 6450.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 90 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6450.5
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6450.55
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 6450.55 with a balance of 0.05.
