Let's divide 99387574 by 580
Our goal is to divide 99387574 by 580.

Let's proceed to step 1:
If we divide 9 by 580, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 580

Advancing to step 2:
580 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 580

Step 3:
580 can be fit into 993 1 times, resulting in a remainder of 413.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 580 away from 993, we end up with 413.
Bring next digit (8) of the dividend behind the 413 and repeat the process: 4138 / 580

Moving on to step 4:
580 can be fit into 4138 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 4060 from 4138 to get 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 580

Moving on to step 5:
If we divide 787 by 580, we get 1 and a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 580 from 787 and we're left with 207.
Include the next digit (5) from the dividend after 207, then repeat: 2075 / 580

Going ahead to step 6:
When dividing 2075 by 580, we get 3 with a remainder of 335.
The next digit of our result is 3. 
Result so far: 1713.0
Subtract 1740 from 2075 to get 335.
Grab the next digit (7) from the dividend, add it to 335, then carry on: 3357 / 580

Let's proceed to step 7:
The number 580 fits into 3357 5 times, leaving a remainder of 457.
Use 5 as the next digit of our solution. 
Result so far: 17135.0
Subtract 2900 from 3357 to get 457.
Bring next digit (4) of the dividend behind the 457 and repeat the process: 4574 / 580

Moving on to step 8:
If we divide 4574 by 580, we get 7 and a remainder of 514.
The next digit of our result is 7. 
Result so far: 171357.0
If we take 4060 away from 4574, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 9:
5140 divided by 580 is 8 with a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 171357.8
The remainder is 500 after subtracting 4640 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
580 can be fit into 5000 8 times, resulting in a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 171357.88
Subtracting 4640 from 5000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 171357.88 and a remainder of 0.36.
