We look at the division of 343260 by 45 
Our goal is to divide 343260 by 45.

Step 1:
3 divided by 45 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 45

Moving on to step 2:
45 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 45

Moving on to step 3:
45 goes into 343 7 times with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 28 after subtracting 315 from 343.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 45

On to step 4:
The number 45 fits into 282 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 12 after subtracting 270 from 282.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 45

Moving on to step 5:
If we divide 126 by 45, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 762.0
Subtracting 90 from 126 leaves us with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 45

Step 6:
45 can be fit into 360 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 7628.0
Subtracting 360 from 360 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 45, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7628.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7628.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7628.0, with a leftover of 0.0.
