We're dividing 80855149 by 45 
We're looking to find how many times 45 goes into 80855149.

Moving on to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 45

Step 2:
45 can be fit into 80 1 times, resulting in a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 80 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 45

Advancing to step 3:
45 can be fit into 358 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 43 after subtracting 315 from 358.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 45

Step 4:
The number 45 fits into 435 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 179.0
The remainder is 30 after subtracting 405 from 435.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 45

Advancing to step 5:
If we divide 305 by 45, we get 6 and a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 1796.0
Deduct 270 from 305 and we're left with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 45

Step 6:
If we divide 351 by 45, we get 7 and a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 17967.0
If we subtract 315 from 351, we get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 45

Advancing to step 7:
The number 45 fits into 364 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 179678.0
Subtract 360 from 364 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 45

Step 8:
45 goes into 49 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1796781.0
Subtracting 45 from 49 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
45 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1796781.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 1796781.08
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 45, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 1796781.088
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 1796781.088 and a remainder of 0.004.
