Going ahead to step 1:
7 divided by 4 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 4

Going ahead to step 2:
4 can be fit into 32 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 32 from 32 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 4

Advancing to step 3:
The number 4 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 4

Going ahead to step 4:
29 divided by 4 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 1807.0
Subtracting 28 from 29 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Going ahead to step 5:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 18072.0
The remainder is 2 after subtracting 8 from 10.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Let's proceed to step 6:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 180726.0
Subtract 24 from 26 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 180726.5
Subtracting 20 from 20 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.

Let's proceed 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: 180726.5
Deduct 0 from 0 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.

Let's proceed to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 180726.5
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.

Our division results in 180726.5 with a remaining 0.0.
