We divide 586814 by 90
We want to divide 586814 by 90.

Going ahead to step 1:
90 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 90

Moving on to step 2:
58 divided by 90 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 90

Going ahead to step 3:
90 can be fit into 586 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 540 from 586, we get 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 90

Advancing to step 4:
468 divided by 90 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 450 from 468 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 90

Advancing to step 5:
When dividing 181 by 90, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 652.0
The remainder is 1 after subtracting 180 from 181.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 90

Step 6:
When dividing 14 by 90, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 6520.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 90 is 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 6520.1
Subtract 90 from 140 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.

Advancing to step 8:
500 divided by 90 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 6520.15
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6520.155
If we subtract 450 from 500, we 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.

The final outcome is 6520.155, with a leftover of 0.005.
