We look at the division of 491451 by 68 
We're looking to find how many times 68 goes into 491451.

Moving on to step 1:
The number 68 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 68

Going ahead to step 2:
68 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 68

Moving on to step 3:
491 divided by 68 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 476 from 491, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 68

Moving on to step 4:
If we divide 154 by 68, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 136 from 154 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 68

Advancing to step 5:
68 can be fit into 185 2 times, resulting in a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 722.0
Subtracting 136 from 185 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 68

On to step 6:
68 goes into 491 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 7227.0
Subtracting 476 from 491 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 68 fits into 150 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 7227.2
Subtracting 136 from 150 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 68, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7227.22
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 7227.22 with a remaining 0.004.
