12111019 divided by 686 
We want to figure out the number of times 12111019 can be divided by 686.

Going ahead to step 1:
If we divide 1 by 686, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 686

Going ahead to step 2:
686 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 686

On to step 3:
121 divided by 686 is 0 with a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 686

Let's proceed to step 4:
The number 686 fits into 1211 1 times, leaving a remainder of 525.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 686 away from 1211, we end up with 525.
Bring next digit (1) of the dividend behind the 525 and repeat the process: 5251 / 686

On to step 5:
If we divide 5251 by 686, we get 7 and a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 4802 from 5251 and we're left with 449.
Fetch the next digit (0) from the dividend, attach it to 449 and continue: 4490 / 686

On to step 6:
686 can be fit into 4490 6 times, resulting in a remainder of 374.
The next digit of our result is 6. 
Result so far: 176.0
Deduct 4116 from 4490 and we're left with 374.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 686

Let's proceed to step 7:
If we divide 3741 by 686, we get 5 and a remainder of 311.
The next digit of our result is 5. 
Result so far: 1765.0
Subtracting 3430 from 3741 leaves us with 311.
Include the next digit (9) from the dividend after 311, then repeat: 3119 / 686

On to step 8:
3119 divided by 686 is 4 with a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 17654.0
If we take 2744 away from 3119, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 9:
686 goes into 3750 5 times with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 17654.5
Subtracting 3430 from 3750 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
3200 divided by 686 is 4 with a remainder of 456.
The number 4 becomes the next digit in our result. 
Result so far: 17654.54
If we take 2744 away from 3200, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 11:
686 goes into 4560 6 times with a remainder of 444.
Put 6 as the next digit of the answer. 
Result so far: 17654.546
Deduct 4116 from 4560 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 12:
If we divide 4440 by 686, we get 6 and a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 17654.5466
The remainder is 324 after subtracting 4116 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 17654.5466 with a balance of 0.00324.
