We're dividing 319040 by 45 
We want to divide 319040 by 45.

Going ahead to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 45

Going ahead to step 2:
31 divided by 45 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 45

Going ahead to step 3:
319 divided by 45 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 315 from 319, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 45

On to step 4:
45 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 45

Step 5:
404 divided by 45 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 708.0
The remainder is 44 after subtracting 360 from 404.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 45

Step 6:
The number 45 fits into 440 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 7089.0
If we subtract 405 from 440, 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.

Advancing to step 7:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 7089.7
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.

Advancing to step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 7089.77
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.

After the division, we end up with 7089.77 and a remainder of 0.035.
