We look at the division of 353943 by 68 
Let's see how many times 68 fits into 353943.

Moving on to step 1:
3 divided by 68 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 68

Going ahead to step 2:
68 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 68

Moving on to step 3:
353 divided by 68 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 13 after subtracting 340 from 353.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 68

Moving on to step 4:
68 can be fit into 139 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 136 away from 139, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 68

Step 5:
68 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 520.0
If we subtract 0 from 34, we get 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 68

Going ahead to step 6:
If we divide 343 by 68, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5205.0
Deduct 340 from 343 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 68, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5205.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
If we divide 300 by 68, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 5205.04
If we take 272 away from 300, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 68, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 5205.044
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 5205.044, and the remainder is 0.0008.
