We divide 313800 by 45
We're looking to find how many times 45 goes into 313800.

On to step 1:
45 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 45

On to step 2:
45 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 45

Step 3:
The number 45 fits into 313 6 times, leaving a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 43 after subtracting 270 from 313.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 45

On to step 4:
The number 45 fits into 438 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 405 from 438 and we're left with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 45

On to step 5:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 697.0
If we subtract 315 from 330, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 45

Moving on to step 6:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 6973.0
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 45, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 6973.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 6973.33
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 6973.33, with a leftover of 0.015.
