98535579 ÷ 580 
Our goal is to divide 98535579 by 580.

Advancing to step 1:
If we divide 9 by 580, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 580

On to step 2:
When dividing 98 by 580, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 580

Step 3:
580 goes into 985 1 times with a remainder of 405.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 580 away from 985, we end up with 405.
Fetch the next digit (3) from the dividend, attach it to 405 and continue: 4053 / 580

Let's proceed to step 4:
If we divide 4053 by 580, we get 6 and a remainder of 573.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3480 from 4053 leaves us with 573.
Take the next digit (5) from the dividend and append it to 573, then repeat: 5735 / 580

Going ahead to step 5:
580 goes into 5735 9 times with a remainder of 515.
Use 9 as the next digit of our solution. 
Result so far: 169.0
If we take 5220 away from 5735, we end up with 515.
Bring next digit (5) of the dividend behind the 515 and repeat the process: 5155 / 580

Step 6:
The number 580 fits into 5155 8 times, leaving a remainder of 515.
Record the quotient 8 as the next digit in the result. 
Result so far: 1698.0
Subtract 4640 from 5155 to get 515.
Include the next digit (7) from the dividend after 515, then repeat: 5157 / 580

Let's proceed to step 7:
580 can be fit into 5157 8 times, resulting in a remainder of 517.
Use 8 as the next digit of our solution. 
Result so far: 16988.0
Subtracting 4640 from 5157 leaves us with 517.
Include the next digit (9) from the dividend after 517, then repeat: 5179 / 580

Going ahead to step 8:
580 can be fit into 5179 8 times, resulting in a remainder of 539.
The next digit of our result is 8. 
Result so far: 169888.0
If we subtract 4640 from 5179, we get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 9:
When dividing 5390 by 580, we get 9 with a remainder of 170.
The next digit of our result is 9. 
Result so far: 169888.9
Subtracting 5220 from 5390 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
When dividing 1700 by 580, we get 2 with a remainder of 540.
Record the quotient 2 as the next digit in the result. 
Result so far: 169888.92
Deduct 1160 from 1700 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
5400 divided by 580 is 9 with a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 169888.929
If we take 5220 away from 5400, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
If we divide 1800 by 580, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 169888.9293
Subtract 1740 from 1800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
580 can be fit into 600 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 169888.92931
The remainder is 20 after subtracting 580 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
580 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 169888.92931
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
The number 580 fits into 2000 3 times, leaving a remainder of 260.
Write down 3 as next digit of the result. 
Result so far: 169888.9293103
If we subtract 1740 from 2000, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
580 can be fit into 2600 4 times, resulting in a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 169888.92931034
If we subtract 2320 from 2600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 169888.92931034 with a remaining 2.8e-07.
