785310 ÷ 45 
Our goal is to divide 785310 by 45.

Going ahead to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 45

Advancing to step 2:
78 divided by 45 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 78 to get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 45

Moving on to step 3:
If we divide 335 by 45, we get 7 and a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 315 from 335, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 45

Let's proceed to step 4:
If we divide 203 by 45, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 174.0
The remainder is 23 after subtracting 180 from 203.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 45

Going ahead to step 5:
The number 45 fits into 231 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 1745.0
The remainder is 6 after subtracting 225 from 231.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 45

Moving on to step 6:
45 can be fit into 60 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 17451.0
If we subtract 45 from 60, we get 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 7:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 17451.3
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
150 divided by 45 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 17451.33
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.

After the division, we end up with 17451.33 and a remainder of 0.015.
