253457 ÷ 68 
Let's see how many times 68 fits into 253457.

On to step 1:
2 divided by 68 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 68

Moving on to step 2:
The number 68 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 68

Going ahead to step 3:
68 goes into 253 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 204 from 253 and we're left with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 68

On to step 4:
68 can be fit into 494 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 476 away from 494, we end up with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 68

Let's proceed to step 5:
185 divided by 68 is 2 with a remainder of 49.
The next digit of our result is 2. 
Result so far: 372.0
Deduct 136 from 185 and we're left with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 68

Moving on to step 6:
68 goes into 497 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 3727.0
If we subtract 476 from 497, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
68 goes into 210 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3727.3
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 68, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3727.3
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
68 can be fit into 600 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 3727.308
Subtracting 544 from 600 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
68 can be fit into 560 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3727.3088
Deduct 544 from 560 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3727.3088, with a leftover of 0.00016.
