641731 ÷ 68 
We're looking to find how many times 68 goes into 641731.

Moving on to step 1:
68 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 68

Going ahead to step 2:
68 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 68

On to step 3:
If we divide 641 by 68, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 612 from 641 and we're left with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 68

Step 4:
297 divided by 68 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 94.0
If we subtract 272 from 297, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 68

Going ahead to step 5:
68 goes into 253 3 times with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 943.0
Subtract 204 from 253 to get 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 68

Going ahead to step 6:
491 divided by 68 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 9437.0
If we subtract 476 from 491, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 68, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 9437.2
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 68, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 9437.22
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 9437.22 with a remainder of 0.004.
