We're dividing 545752 by 45 
Let's see how many times 45 fits into 545752.

Going ahead to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 45

Moving on to step 2:
54 divided by 45 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 45 from 54.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 45

Step 3:
45 goes into 95 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 90 away from 95, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 45

Let's proceed to step 4:
45 can be fit into 57 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 45 from 57 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 45

Let's proceed to step 5:
If we divide 125 by 45, we get 2 and a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 1212.0
Subtract 90 from 125 to get 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 45

Advancing to step 6:
When dividing 352 by 45, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 12127.0
Subtract 315 from 352 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
45 goes into 370 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 12127.8
Subtract 360 from 370 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12127.82
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 12127.822
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 12127.822, with a leftover of 0.001.
