317555 ÷ 45 
Let's see how many times 45 fits into 317555.

Step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 45

Step 2:
45 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 45

Step 3:
45 goes into 317 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 315 from 317 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 45

Step 4:
When dividing 25 by 45, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtract 0 from 25 to get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 45

Moving on to step 5:
45 can be fit into 255 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 705.0
Subtracting 225 from 255 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 45

Going ahead to step 6:
45 can be fit into 305 6 times, resulting in a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 7056.0
Deduct 270 from 305 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.

Advancing to step 7:
350 divided by 45 is 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 7056.7
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.

Advancing to step 8:
If we divide 350 by 45, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 7056.77
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.

The final result is 7056.77 with a remainder of 0.035.
