580385 ÷ 48 
We're looking to find how many times 48 goes into 580385.

Advancing to step 1:
When dividing 5 by 48, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 48

Going ahead to step 2:
48 can be fit into 58 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 48 from 58 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 48

On to step 3:
100 divided by 48 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 96 from 100 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 48

Going ahead to step 4:
When dividing 43 by 48, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 43 to get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 48

On to step 5:
The number 48 fits into 438 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1209.0
Subtracting 432 from 438 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 48

Advancing to step 6:
The number 48 fits into 65 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 12091.0
The remainder is 17 after subtracting 48 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 48 fits into 170 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 12091.3
Subtracting 144 from 170 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
48 can be fit into 260 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 12091.35
If we subtract 240 from 260, we get 20.
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 9:
200 divided by 48 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 12091.354
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
48 can be fit into 80 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 12091.3541
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 12091.35416
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
If we divide 320 by 48, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 12091.354166
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 12091.354166 and a remainder of 3.2e-06.
