348863 ÷ 45 
Let's see how many times 45 fits into 348863.

Going ahead to step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 45

On to step 2:
The number 45 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 45

Let's proceed to step 3:
When dividing 348 by 45, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 315 from 348 and we're left with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 45

Going ahead to step 4:
If we divide 338 by 45, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we take 315 away from 338, we end up with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 45

Going ahead to step 5:
45 can be fit into 236 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 775.0
Deduct 225 from 236 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 45

Let's proceed to step 6:
The number 45 fits into 113 2 times, leaving a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 7752.0
Subtracting 90 from 113 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 45 fits into 230 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7752.5
If we take 225 away from 230, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 7752.51
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 7752.511
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 7752.511 with a remainder of 0.0005.
