We divide 817404 by 45
Let's see how many times 45 fits into 817404.

Let's proceed to step 1:
45 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 45

Step 2:
45 goes into 81 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 36 after subtracting 45 from 81.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 45

On to step 3:
If we divide 367 by 45, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 360 from 367 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 45

Advancing to step 4:
When dividing 74 by 45, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Deduct 45 from 74 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 45

On to step 5:
45 goes into 290 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 1816.0
If we subtract 270 from 290, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 45

Advancing to step 6:
The number 45 fits into 204 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 18164.0
Deduct 180 from 204 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
If we divide 240 by 45, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 18164.5
If we take 225 away from 240, 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.

Moving on to step 8:
45 goes into 150 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 18164.53
If we subtract 135 from 150, 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 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18164.533
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 outcome is 18164.533, with a leftover of 0.0015.
