Let's divide 810771 by 45
We want to figure out the number of times 810771 can be divided by 45.

Advancing to step 1:
8 divided by 45 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

Step 2:
When dividing 81 by 45, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 81 to get 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 45

On to step 3:
If we divide 360 by 45, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 360 from 360 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 45

Advancing to step 4:
If we divide 7 by 45, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 45

Advancing to step 5:
The number 45 fits into 77 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1801.0
Subtracting 45 from 77 leaves us with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 45

Moving on to step 6:
If we divide 321 by 45, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 18017.0
Subtracting 315 from 321 leaves us 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.

Going ahead to step 7:
The number 45 fits into 60 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 18017.1
If we subtract 45 from 60, we get 15.
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 8:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 18017.13
If we take 135 away from 150, we end up 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.

Advancing to step 9:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 18017.133
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.

The final result is 18017.133 with a remainder of 0.0015.
