We divide 802589 by 45
We're looking to find how many times 45 goes into 802589.

Going ahead to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 45

Moving on to step 2:
When dividing 80 by 45, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 80, we end up with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 45

Going ahead to step 3:
If we divide 352 by 45, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 37 after subtracting 315 from 352.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 45

Let's proceed to step 4:
When dividing 375 by 45, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we take 360 away from 375, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 45

Step 5:
158 divided by 45 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 1783.0
If we take 135 away from 158, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Going ahead to step 6:
45 goes into 239 5 times with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 17835.0
The remainder is 14 after subtracting 225 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 45 fits into 140 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 17835.3
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
45 goes into 50 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 17835.31
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 45, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 17835.311
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 17835.311 with a balance of 0.0005.
