We look at the division of 648621 by 68 
We're looking to find how many times 68 goes into 648621.

Let's proceed to step 1:
68 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 68

Advancing to step 2:
When dividing 64 by 68, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 68

Moving on to step 3:
648 divided by 68 is 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 612 away from 648, we end up with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 68

Advancing to step 4:
The number 68 fits into 366 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 340 from 366, we get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 68

Going ahead to step 5:
When dividing 262 by 68, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 953.0
Subtracting 204 from 262 leaves us with 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 68

Let's proceed to step 6:
If we divide 581 by 68, we get 8 and a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 9538.0
The remainder is 37 after subtracting 544 from 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
When dividing 370 by 68, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9538.5
If we take 340 away from 370, we end up with 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:
68 goes into 300 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 9538.54
The remainder is 28 after subtracting 272 from 300.
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:
68 can be fit into 280 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 9538.544
If we subtract 272 from 280, we get 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 final result is 9538.544 with a remainder of 0.0008.
