We divide 810531 by 45
Our goal is to divide 810531 by 45.

Moving on to step 1:
45 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 45

Let's proceed to step 2:
81 divided by 45 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 36 after subtracting 45 from 81.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 45

Moving on to step 3:
The number 45 fits into 360 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 360 from 360, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 45

Let's proceed to step 4:
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: 180.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 45

Step 5:
The number 45 fits into 53 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1801.0
The remainder is 8 after subtracting 45 from 53.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 45

Going ahead to step 6:
45 goes into 81 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 18011.0
The remainder is 36 after subtracting 45 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
45 goes into 360 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18011.8
Subtract 360 from 360 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.

Advancing to step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18011.8
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.

Advancing to step 9:
When dividing 0 by 45, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18011.8
If we subtract 0 from 0, 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.

In conclusion, the division gives 18011.8 with a balance of 0.0.
