518601 divided by 45 
Let's see how many times 45 fits into 518601.

On to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Let's proceed to step 2:
45 goes into 51 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 51 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 45

Let's proceed to step 3:
The number 45 fits into 68 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 45 from 68 and we're left with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 45

Let's proceed to step 4:
If we divide 236 by 45, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we subtract 225 from 236, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 45

On to step 5:
45 goes into 110 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
If we subtract 90 from 110, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 45

Advancing to step 6:
If we divide 201 by 45, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 11524.0
Subtracting 180 from 201 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 45, we get 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 11524.4
If we subtract 180 from 210, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 45 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 11524.46
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 11524.466
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 11524.466 and a remainder of 0.003.
