We divide 808836 by 45
We're looking to find how many times 45 goes into 808836.

Let's proceed to step 1:
If we divide 8 by 45, we get 0 and 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.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

On to step 2:
When dividing 80 by 45, we get 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 80, we end up with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 45

Step 3:
358 divided by 45 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 315 away from 358, we end up with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 45

Moving on to step 4:
When dividing 438 by 45, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
If we subtract 405 from 438, we get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 45

Going ahead to step 5:
If we divide 333 by 45, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 1797.0
The remainder is 18 after subtracting 315 from 333.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 45

Advancing to step 6:
186 divided by 45 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 17974.0
Subtracting 180 from 186 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:
45 can be fit into 60 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 17974.1
If we take 45 away from 60, 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.

On to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17974.13
Deduct 135 from 150 and we're left 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.

Going ahead to step 9:
150 divided by 45 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17974.133
Subtracting 135 from 150 leaves us 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.

After the division, we end up with 17974.133 and a remainder of 0.0015.
