We look at the division of 68686780 by 641 
We want to figure out the number of times 68686780 can be divided by 641.

Moving on to step 1:
641 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 641

On to step 2:
68 divided by 641 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 641

Step 3:
641 can be fit into 686 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 641 away from 686, we end up with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 641

Moving on to step 4:
641 goes into 458 0 times with a remainder of 458.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 458 to get 458.
Grab the next digit (6) from the dividend, add it to 458, then carry on: 4586 / 641

Going ahead to step 5:
If we divide 4586 by 641, we get 7 and a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 4487 from 4586 leaves us with 99.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 641

Let's proceed to step 6:
641 goes into 997 1 times with a remainder of 356.
Use 1 as the next digit of our solution. 
Result so far: 1071.0
Subtracting 641 from 997 leaves us with 356.
Take the next digit (8) from the dividend and append it to 356, then repeat: 3568 / 641

Going ahead to step 7:
If we divide 3568 by 641, we get 5 and a remainder of 363.
Put 5 as the next digit of the answer. 
Result so far: 10715.0
Subtract 3205 from 3568 to get 363.
Grab the next digit (0) from the dividend, add it to 363, then carry on: 3630 / 641

On to step 8:
The number 641 fits into 3630 5 times, leaving a remainder of 425.
The next digit of our result is 5. 
Result so far: 107155.0
Deduct 3205 from 3630 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 9:
The number 641 fits into 4250 6 times, leaving a remainder of 404.
Put 6 as the next digit of the answer. 
Result so far: 107155.6
If we take 3846 away from 4250, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 10:
When dividing 4040 by 641, we get 6 with a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 107155.66
Subtracting 3846 from 4040 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The quotient of the division is 107155.66, and the remainder is 0.194.
