We divide 773 by 45
We want to figure out the number of times 773 can be divided by 45.

Step 1:
7 divided by 45 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 45

Moving on to step 2:
77 divided by 45 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 77 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 45

Let's proceed to step 3:
If we divide 323 by 45, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 315 from 323 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 4:
45 goes into 80 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 17.1
If we take 45 away from 80, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 5:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 17.17
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 6:
When dividing 350 by 45, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 17.177
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 17.177 and a remainder of 0.0035.
