486671 divided by 45 
Our goal is to divide 486671 by 45.

Going ahead to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 45

Advancing to step 2:
48 divided by 45 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 48, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 45

Step 3:
The number 45 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 45

Let's proceed to step 4:
If we divide 366 by 45, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 360 from 366 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 45

On to step 5:
45 goes into 67 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1081.0
If we subtract 45 from 67, we get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 45

Going ahead to step 6:
If we divide 221 by 45, we get 4 and a remainder of 41.
The next digit of our result is 4. 
Result so far: 10814.0
If we subtract 180 from 221, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
If we divide 410 by 45, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 10814.9
If we take 405 away from 410, we end up 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 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 10814.91
If we take 45 away from 50, we end up 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.

Let's proceed to step 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 10814.911
Deduct 45 from 50 and we're left 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.

The quotient of the division is 10814.911, and the remainder is 0.0005.
