803180 ÷ 45 
We're looking to find how many times 45 goes into 803180.

Advancing to step 1:
8 divided by 45 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 45

On to step 2:
45 can be fit into 80 1 times, resulting in a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 35 after subtracting 45 from 80.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 45

On to step 3:
45 goes into 353 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 315 away from 353, we end up with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 45

Going ahead to step 4:
When dividing 381 by 45, we get 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Subtracting 360 from 381 leaves us with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 45

Step 5:
If we divide 218 by 45, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 1784.0
The remainder is 38 after subtracting 180 from 218.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 45

Let's proceed to step 6:
380 divided by 45 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 17848.0
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
45 goes into 200 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 17848.4
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 17848.44
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 17848.44 with a remainder of 0.02.
