We divide 543168 by 45
Let's see how many times 45 fits into 543168.

On to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 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 2:
54 divided by 45 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 54 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 45

Advancing to step 3:
45 can be fit into 93 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 90 from 93 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 45

Let's proceed to step 4:
31 divided by 45 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 120.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 45

Let's proceed to step 5:
45 goes into 316 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1207.0
Subtracting 315 from 316 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 45

Moving on to step 6:
If we divide 18 by 45, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 12070.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 45 fits into 180 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 12070.4
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 45 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12070.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
45 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12070.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12070.4 and a remainder of 0.0.
