348257 ÷ 7 
Let's see how many times 7 fits into 348257.

On to step 1:
7 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 7

Step 2:
34 divided by 7 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 28 from 34 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 7

Going ahead to step 3:
When dividing 68 by 7, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 5 after subtracting 63 from 68.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 7

On to step 4:
If we divide 52 by 7, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 497.0
The remainder is 3 after subtracting 49 from 52.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 7

Advancing to step 5:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4975.0
If we subtract 35 from 35, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

Advancing to step 6:
7 divided by 7 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 49751.0
Deduct 7 from 7 and we're left 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.

Moving on to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 49751.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49751.0
The remainder is 0 after subtracting 0 from 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 49751.0, with a leftover of 0.0.
