Let's divide 17123485 by 580
We want to figure out the number of times 17123485 can be divided by 580.

Moving on to step 1:
580 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 580

Going ahead to step 2:
580 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 580

On to step 3:
580 goes into 171 0 times with a remainder of 171.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 171, we get 171.
Append the next digit (2) from the dividend to 171 and continue with: 1712 / 580

On to step 4:
If we divide 1712 by 580, we get 2 and a remainder of 552.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1160 from 1712 leaves us with 552.
Bring next digit (3) of the dividend behind the 552 and repeat the process: 5523 / 580

Advancing to step 5:
580 can be fit into 5523 9 times, resulting in a remainder of 303.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 5220 from 5523 to get 303.
Include the next digit (4) from the dividend after 303, then repeat: 3034 / 580

Going ahead to step 6:
If we divide 3034 by 580, we get 5 and a remainder of 134.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
Subtracting 2900 from 3034 leaves us with 134.
Include the next digit (8) from the dividend after 134, then repeat: 1348 / 580

Advancing to step 7:
If we divide 1348 by 580, we get 2 and a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 2952.0
Deduct 1160 from 1348 and we're left with 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 580

Moving on to step 8:
When dividing 1885 by 580, we get 3 with a remainder of 145.
Use 3 as the next digit of our solution. 
Result so far: 29523.0
Deduct 1740 from 1885 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
When dividing 1450 by 580, we get 2 with a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 29523.2
If we take 1160 away from 1450, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
When dividing 2900 by 580, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 29523.25
Subtract 2900 from 2900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 580 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29523.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
The number 580 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29523.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 29523.25, and the remainder is 0.0.
