Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 93

Advancing to step 2:
40 divided by 93 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 93

Advancing to step 3:
406 divided by 93 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 372 from 406 to get 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 93

On to step 4:
343 divided by 93 is 3 with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 279 from 343 and we're left with 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 93

Let's proceed to step 5:
648 divided by 93 is 6 with a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Deduct 558 from 648 and we're left with 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 93

Advancing to step 6:
When dividing 909 by 93, we get 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 4369.0
The remainder is 72 after subtracting 837 from 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
If we divide 720 by 93, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 4369.7
Subtracting 651 from 720 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
690 divided by 93 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 4369.77
Subtracting 651 from 690 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 4369.77 and a remainder of 0.039.
