We're dividing 855511 by 45 
We want to divide 855511 by 45.

Let's proceed to step 1:
If we divide 8 by 45, we get 0 and 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.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 45

Step 2:
85 divided by 45 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 40 after subtracting 45 from 85.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 45

Moving on to step 3:
If we divide 405 by 45, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 405 from 405 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 45

Going ahead to step 4:
If we divide 5 by 45, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Advancing to step 5:
51 divided by 45 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1901.0
If we subtract 45 from 51, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 45

Going ahead to step 6:
45 can be fit into 61 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 19011.0
Subtracting 45 from 61 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
45 can be fit into 160 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 19011.3
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
45 goes into 250 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 19011.35
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
45 goes into 250 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 19011.355
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 19011.355, and the remainder is 0.0025.
