555513 divided by 45 
Let's see how many times 45 fits into 555513.

Moving on to step 1:
5 divided by 45 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 45

Let's proceed to step 2:
If we divide 55 by 45, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 55 to get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 45

Advancing to step 3:
45 goes into 105 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 90 from 105 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 45

Let's proceed to step 4:
If we divide 155 by 45, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 135 away from 155, we end up with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 45

Moving on to step 5:
If we divide 201 by 45, we get 4 and a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 1234.0
Subtract 180 from 201 to get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 45

Going ahead to step 6:
45 can be fit into 213 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 12344.0
Subtract 180 from 213 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 12344.7
Deduct 315 from 330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 12344.73
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 12344.733
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 12344.733, with a leftover of 0.0015.
