We're dividing 90580 by 84 
Our goal is to divide 90580 by 84.

Moving on to step 1:
The number 84 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 84

Step 2:
The number 84 fits into 90 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 84 from 90, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 84

Let's proceed to step 3:
The number 84 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 65 to get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 84

Moving on to step 4:
658 divided by 84 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 588 from 658, we get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 84

Step 5:
The number 84 fits into 700 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1078.0
Deduct 672 from 700 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
84 goes into 280 3 times with a remainder of 28.
The next digit of our result is 3. 
Result so far: 1078.3
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
280 divided by 84 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1078.33
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 1078.33 with a balance of 0.028.
