343657 ÷ 68 
Let's see how many times 68 fits into 343657.

Going ahead to step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 68

Moving on to step 2:
If we divide 34 by 68, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 68

Step 3:
68 goes into 343 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 340 from 343 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 68

Going ahead to step 4:
The number 68 fits into 36 0 times, leaving a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 36 and we're left with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 68

Step 5:
When dividing 365 by 68, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 505.0
If we subtract 340 from 365, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 68

On to step 6:
257 divided by 68 is 3 with a remainder of 53.
The next digit of our result is 3. 
Result so far: 5053.0
If we subtract 204 from 257, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 68 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5053.7
Subtracting 476 from 530 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
68 can be fit into 540 7 times, resulting in a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 5053.77
If we take 476 away from 540, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 5053.77 with a remaining 0.064.
