17578 divided by 4 
We want to figure out the number of times 17578 can be divided by 4.

Let's proceed to step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 4

Moving on to step 2:
17 divided by 4 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 16 from 17 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

On to step 3:
15 divided by 4 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 3 after subtracting 12 from 15.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 4

Step 4:
The number 4 fits into 37 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
Deduct 36 from 37 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Moving on to step 5:
If we divide 18 by 4, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4394.0
If we take 16 away from 18, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4394.5
Deduct 20 from 20 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4394.5
Subtract 0 from 0 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.

Moving on to step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4394.5
Subtracting 0 from 0 leaves us with 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 final result is 4394.5 with a remainder of 0.0.
