We divide 543208 by 45
We're looking to find how many times 45 goes into 543208.

Going ahead to step 1:
When dividing 5 by 45, we get 0 with 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

Moving on to step 2:
The number 45 fits into 54 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 54 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 45

Going ahead to step 3:
45 can be fit into 93 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 90 from 93 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 45

On to step 4:
When dividing 32 by 45, we get 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtract 0 from 32 to get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 45

Going ahead to step 5:
The number 45 fits into 320 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 1207.0
If we subtract 315 from 320, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 45

Going ahead to step 6:
When dividing 58 by 45, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 12071.0
The remainder is 13 after subtracting 45 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
45 can be fit into 130 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 12071.2
If we subtract 90 from 130, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12071.28
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
45 goes into 400 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 12071.288
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 12071.288 and a remainder of 0.004.
