We look at the division of 644742 by 68 
We want to figure out the number of times 644742 can be divided by 68.

Advancing to step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 68

Moving on to step 2:
When dividing 64 by 68, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 68

Going ahead to step 3:
When dividing 644 by 68, we get 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 32 after subtracting 612 from 644.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 68

Going ahead to step 4:
327 divided by 68 is 4 with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 272 from 327, we get 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 68

Advancing to step 5:
When dividing 554 by 68, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 948.0
If we subtract 544 from 554, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 68

Moving on to step 6:
68 goes into 102 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 9481.0
Subtract 68 from 102 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
68 goes into 340 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9481.5
Subtracting 340 from 340 leaves us 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.

Let's proceed to step 8:
The number 68 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9481.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
68 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9481.5
Subtracting 0 from 0 leaves us 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.

Our division results in 9481.5 with a remaining 0.0.
