Let's divide 856770 by 45
Our goal is to divide 856770 by 45.

Step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 45

Let's proceed to step 2:
85 divided by 45 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 85, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 45

Going ahead to step 3:
406 divided by 45 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 405 from 406 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 45

Going ahead to step 4:
If we divide 17 by 45, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtract 0 from 17 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 45

Let's proceed to step 5:
177 divided by 45 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1903.0
If we take 135 away from 177, we end up with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 45

Advancing to step 6:
If we divide 420 by 45, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 19039.0
Deduct 405 from 420 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.

Let's proceed to step 7:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 19039.3
If we take 135 away from 150, 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 can be fit into 150 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 19039.33
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 19039.33, with a leftover of 0.015.
