504203 ÷ 45 
We want to divide 504203 by 45.

Moving on to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 45

Let's proceed to step 2:
45 goes into 50 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 50 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 45

On to step 3:
When dividing 54 by 45, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 9 after subtracting 45 from 54.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 45

Advancing to step 4:
The number 45 fits into 92 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 90 away from 92, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 45

On to step 5:
45 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1120.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 45

Let's proceed to step 6:
45 can be fit into 203 4 times, resulting in a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 11204.0
Subtract 180 from 203 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
When dividing 230 by 45, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 11204.5
Subtract 225 from 230 to get 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 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 11204.51
Subtracting 45 from 50 leaves us 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.

On to step 9:
50 divided by 45 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 11204.511
Subtracting 45 from 50 leaves us 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.

In conclusion, the division gives 11204.511 with a balance of 0.0005.
