858500 divided by 45 
We're looking to find how many times 45 goes into 858500.

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 subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 45

Let's proceed to step 2:
When dividing 85 by 45, we get 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 85 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 45

On to step 3:
If we divide 408 by 45, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 405 from 408, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 45

Let's proceed to step 4:
The number 45 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 35, we get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 45

Let's proceed to step 5:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 1907.0
Subtracting 315 from 350 leaves us with 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 45

Step 6:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 19077.0
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 19077.7
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 19077.77
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 19077.77 with a balance of 0.035.
