We divide 549502 by 45
Our goal is to divide 549502 by 45.

On to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 45

Step 2:
If we divide 54 by 45, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 9 after subtracting 45 from 54.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 45

Advancing to step 3:
When dividing 99 by 45, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 90 from 99 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 45

On to step 4:
If we divide 95 by 45, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 90 from 95 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 45

On to step 5:
If we divide 50 by 45, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
If we take 45 away from 50, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 45

Going ahead to step 6:
52 divided by 45 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 12211.0
The remainder is 7 after subtracting 45 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
45 can be fit into 70 1 times, resulting in a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 12211.1
Deduct 45 from 70 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12211.15
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12211.155
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 12211.155, with a leftover of 0.0025.
