570617 ÷ 45 
Our goal is to divide 570617 by 45.

Advancing to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 45

Moving on to step 2:
45 can be fit into 57 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 57 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 45

Let's proceed to step 3:
120 divided by 45 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 90 away from 120, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 45

Advancing to step 4:
If we divide 306 by 45, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 270 from 306 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 45

On to step 5:
361 divided by 45 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 1268.0
If we take 360 away from 361, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 45

Moving on to step 6:
45 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 12680.0
Deduct 0 from 17 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
When dividing 170 by 45, we get 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 12680.3
Deduct 135 from 170 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.

Step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 12680.37
If we take 315 away from 350, 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.

Step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 12680.377
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 12680.377, with a leftover of 0.0035.
