Let's divide 85020273 by 580
Our goal is to divide 85020273 by 580.

Step 1:
When dividing 8 by 580, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 580

On to step 2:
85 divided by 580 is 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 580

Advancing to step 3:
When dividing 850 by 580, we get 1 with a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 580 from 850 and we're left with 270.
Take the next digit (2) from the dividend and append it to 270, then repeat: 2702 / 580

Going ahead to step 4:
580 can be fit into 2702 4 times, resulting in a remainder of 382.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2320 away from 2702, we end up with 382.
Include the next digit (0) from the dividend after 382, then repeat: 3820 / 580

Step 5:
580 can be fit into 3820 6 times, resulting in a remainder of 340.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we subtract 3480 from 3820, we get 340.
Include the next digit (2) from the dividend after 340, then repeat: 3402 / 580

Advancing to step 6:
580 goes into 3402 5 times with a remainder of 502.
Record the quotient 5 as the next digit in the result. 
Result so far: 1465.0
Subtract 2900 from 3402 to get 502.
Take the next digit (7) from the dividend and append it to 502, then repeat: 5027 / 580

On to step 7:
When dividing 5027 by 580, we get 8 with a remainder of 387.
Put 8 as the next digit of the answer. 
Result so far: 14658.0
If we take 4640 away from 5027, we end up with 387.
Fetch the next digit (3) from the dividend, attach it to 387 and continue: 3873 / 580

Moving on to step 8:
580 can be fit into 3873 6 times, resulting in a remainder of 393.
Write down 6 as next digit of the result. 
Result so far: 146586.0
If we take 3480 away from 3873, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 9:
When dividing 3930 by 580, we get 6 with a remainder of 450.
The number 6 becomes the next digit in our result. 
Result so far: 146586.6
Deduct 3480 from 3930 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
580 goes into 4500 7 times with a remainder of 440.
Put 7 as the next digit of the answer. 
Result so far: 146586.67
If we subtract 4060 from 4500, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
If we divide 4400 by 580, we get 7 and a remainder of 340.
The next digit of our result is 7. 
Result so far: 146586.677
Subtracting 4060 from 4400 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 146586.677, and the remainder is 0.034.
