We're dividing 88313945 by 609 
Let's see how many times 609 fits into 88313945.

Going ahead to step 1:
If we divide 8 by 609, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 609

Let's proceed to step 2:
When dividing 88 by 609, we get 0 with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 609

Going ahead to step 3:
The number 609 fits into 883 1 times, leaving a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 609 from 883 and we're left with 274.
Fetch the next digit (1) from the dividend, attach it to 274 and continue: 2741 / 609

Step 4:
609 can be fit into 2741 4 times, resulting in a remainder of 305.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2436 from 2741 leaves us with 305.
Include the next digit (3) from the dividend after 305, then repeat: 3053 / 609

Moving on to step 5:
3053 divided by 609 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
If we take 3045 away from 3053, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 609

Moving on to step 6:
609 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 1450.0
If we take 0 away from 89, we end up with 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 609

Step 7:
609 goes into 894 1 times with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 14501.0
The remainder is 285 after subtracting 609 from 894.
Include the next digit (5) from the dividend after 285, then repeat: 2855 / 609

Advancing to step 8:
When dividing 2855 by 609, we get 4 with a remainder of 419.
Record the quotient 4 as the next digit in the result. 
Result so far: 145014.0
If we take 2436 away from 2855, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 9:
609 can be fit into 4190 6 times, resulting in a remainder of 536.
The number 6 becomes the next digit in our result. 
Result so far: 145014.6
If we take 3654 away from 4190, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 10:
The number 609 fits into 5360 8 times, leaving a remainder of 488.
Put 8 as the next digit of the answer. 
Result so far: 145014.68
If we subtract 4872 from 5360, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
If we divide 4880 by 609, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 145014.688
If we take 4872 away from 4880, 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.

The final outcome is 145014.688, with a leftover of 0.0008.
