486018 ÷ 45 
We want to figure out the number of times 486018 can be divided by 45.

Advancing to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 45

Step 2:
45 goes into 48 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 48 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 45

Advancing to step 3:
The number 45 fits into 36 0 times, leaving a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 45

Going ahead to step 4:
360 divided by 45 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtracting 360 from 360 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 45

On to step 5:
1 divided by 45 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1080.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

Going ahead to step 6:
18 divided by 45 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10800.0
Deduct 0 from 18 and we're left with 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: 10800.4
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.

Step 8:
0 divided by 45 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10800.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 45 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10800.4
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 10800.4 and a remainder of 0.0.
