We look at the division of 786780 by 45 
Our goal is to divide 786780 by 45.

Moving on to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 45

On to step 2:
When dividing 78 by 45, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 78 and we're left with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 45

On to step 3:
336 divided by 45 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 315 from 336, we get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 45

Advancing to step 4:
45 goes into 217 4 times with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 174.0
Subtracting 180 from 217 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 45

Moving on to step 5:
The number 45 fits into 378 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1748.0
Subtract 360 from 378 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 45

Let's proceed to step 6:
180 divided by 45 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 17484.0
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 45, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17484.0
If we take 0 away from 0, we end up 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.

Moving on to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17484.0
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.

The final outcome is 17484.0, with a leftover of 0.0.
