486141 divided by 45 
Let's see how many times 45 fits into 486141.

On 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
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

Going ahead to step 2:
If we divide 48 by 45, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 45

Step 3:
45 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 45

Step 4:
If we divide 361 by 45, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 108.0
If we take 360 away from 361, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 45

On to step 5:
If we divide 14 by 45, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 1080.0
If we subtract 0 from 14, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 45

Let's proceed to step 6:
The number 45 fits into 141 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 10803.0
If we take 135 away from 141, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 45 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 10803.1
The remainder is 15 after subtracting 45 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 10803.13
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 10803.133
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 10803.133 and a remainder of 0.0015.
