We look at the division of 645305 by 45 
Let's see how many times 45 fits into 645305.

Step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 45

Let's proceed to step 2:
64 divided by 45 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 64, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 45

Step 3:
If we divide 195 by 45, we get 4 and a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 180 from 195 leaves us with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 45

On to step 4:
If we divide 153 by 45, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Deduct 135 from 153 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 45

Let's proceed to step 5:
The number 45 fits into 180 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1434.0
If we take 180 away from 180, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 45

Going ahead to step 6:
45 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 14340.0
If we take 0 away from 5, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 14340.1
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 14340.11
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 14340.11, with a leftover of 0.005.
