We're dividing 68453563 by 309 
Let's see how many times 309 fits into 68453563.

On to step 1:
If we divide 6 by 309, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 309

Going ahead to step 2:
309 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 309

Advancing to step 3:
If we divide 684 by 309, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 618 from 684, we get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 309

Let's proceed to step 4:
309 goes into 665 2 times with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 618 from 665 to get 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 309

Moving on to step 5:
When dividing 473 by 309, we get 1 with a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 221.0
Deduct 309 from 473 and we're left with 164.
Grab the next digit (5) from the dividend, add it to 164, then carry on: 1645 / 309

Step 6:
If we divide 1645 by 309, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 2215.0
If we subtract 1545 from 1645, we get 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 309

Moving on to step 7:
If we divide 1006 by 309, we get 3 and a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 22153.0
If we take 927 away from 1006, we end up with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 309

On to step 8:
When dividing 793 by 309, we get 2 with a remainder of 175.
The number 2 becomes the next digit in our result. 
Result so far: 221532.0
The remainder is 175 after subtracting 618 from 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
1750 divided by 309 is 5 with a remainder of 205.
The next digit of our result is 5. 
Result so far: 221532.5
Subtracting 1545 from 1750 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 10:
If we divide 2050 by 309, we get 6 and a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 221532.56
Subtracting 1854 from 2050 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
1960 divided by 309 is 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 221532.566
Deduct 1854 from 1960 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final outcome is 221532.566, with a leftover of 0.0106.
