Let's divide 770573 by 45
Our goal is to divide 770573 by 45.

Step 1:
45 can be fit into 7 0 times, resulting in 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.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 45

Let's proceed to step 2:
45 can be fit into 77 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 77, we get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 45

Step 3:
320 divided by 45 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 315 from 320 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 45

Step 4:
45 can be fit into 55 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 171.0
Subtract 45 from 55 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 45

On to step 5:
The number 45 fits into 107 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1712.0
Subtract 90 from 107 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 45

Step 6:
173 divided by 45 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 17123.0
If we subtract 135 from 173, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 45 fits into 380 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 17123.8
Deduct 360 from 380 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 17123.84
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17123.844
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 17123.844 with a remaining 0.002.
