We're dividing 686521 by 68 
We want to figure out the number of times 686521 can be divided by 68.

On to step 1:
6 divided by 68 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 68

On to step 2:
68 goes into 68 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 68 from 68 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 68

Moving on to step 3:
The number 68 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 68

Step 4:
68 can be fit into 65 0 times, resulting in a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 68

Step 5:
68 goes into 652 9 times with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 1009.0
If we subtract 612 from 652, we get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 68

On to step 6:
68 goes into 401 5 times with a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 10095.0
The remainder is 61 after subtracting 340 from 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
68 can be fit into 610 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 10095.8
Subtracting 544 from 610 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
660 divided by 68 is 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 10095.89
If we take 612 away from 660, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
68 can be fit into 480 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 10095.897
If we take 476 away from 480, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 68, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10095.897
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 10095.89705
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
When dividing 600 by 68, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 10095.897058
Subtract 544 from 600 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
When dividing 560 by 68, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10095.8970588
Deduct 544 from 560 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 10095.8970588, with a leftover of 1.6e-07.
