We look at the division of 858744 by 45 
We're looking to find how many times 45 goes into 858744.

Moving on to step 1:
8 divided by 45 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 45

Let's proceed to step 2:
If we divide 85 by 45, we get 1 and a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 85 and we're left with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 45

Step 3:
45 goes into 408 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 405 from 408 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 45

Let's proceed to step 4:
37 divided by 45 is 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 37, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 45

On to step 5:
45 goes into 374 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1908.0
Subtract 360 from 374 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 45

Let's proceed to step 6:
45 goes into 144 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 19083.0
Subtract 135 from 144 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 45 fits into 90 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 19083.2
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 19083.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 45, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19083.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 19083.2 with a balance of 0.0.
