Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 88

Moving on to step 2:
If we divide 30 by 88, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.

309 divided by 88 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 45 after subtracting 264 from 309.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 88

Moving on to step 4:
88 goes into 451 5 times with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 440 from 451 and we're left with 11.

Moving on to step 5:
When dividing 112 by 88, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 351.0
Deduct 88 from 112 and we're left with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 88

Let's proceed to step 6:
When dividing 244 by 88, we get 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 3512.0
Subtracting 176 from 244 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
If we divide 680 by 88, we get 7 and a remainder of 64.
The next digit of our result is 7. 
Result so far: 3512.7
Subtract 616 from 680 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
The number 88 fits into 640 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 3512.77
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 3512.77, with a leftover of 0.024.
