We divide 12059974 by 686
We're looking to find how many times 686 goes into 12059974.

On 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
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 686

Let's proceed to step 2:
When dividing 12 by 686, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 686

Going ahead to step 3:
686 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Append the next digit (5) from the dividend to 120 and continue with: 1205 / 686

Let's proceed to step 4:
686 goes into 1205 1 times with a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 686 from 1205 to get 519.
Fetch the next digit (9) from the dividend, attach it to 519 and continue: 5199 / 686

Moving on to step 5:
The number 686 fits into 5199 7 times, leaving a remainder of 397.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 4802 away from 5199, we end up with 397.
Fetch the next digit (9) from the dividend, attach it to 397 and continue: 3979 / 686

Let's proceed to step 6:
3979 divided by 686 is 5 with a remainder of 549.
The next digit of our result is 5. 
Result so far: 175.0
The remainder is 549 after subtracting 3430 from 3979.
Grab the next digit (7) from the dividend, add it to 549, then carry on: 5497 / 686

Step 7:
5497 divided by 686 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 1758.0
Subtract 5488 from 5497 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 686

Advancing to step 8:
When dividing 94 by 686, we get 0 with a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 17580.0
Subtract 0 from 94 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
When dividing 940 by 686, we get 1 with a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 17580.1
If we subtract 686 from 940, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 10:
2540 divided by 686 is 3 with a remainder of 482.
Use 3 as the next digit of our solution. 
Result so far: 17580.13
Subtracting 2058 from 2540 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 11:
4820 divided by 686 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 17580.137
Deduct 4802 from 4820 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 686, we get 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 17580.137
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
686 can be fit into 1800 2 times, resulting in a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 17580.13702
If we subtract 1372 from 1800, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 14:
When dividing 4280 by 686, we get 6 with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 17580.137026
Subtract 4116 from 4280 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
The number 686 fits into 1640 2 times, leaving a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 17580.1370262
Deduct 1372 from 1640 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 16:
2680 divided by 686 is 3 with a remainder of 622.
Use 3 as the next digit of our solution. 
Result so far: 17580.13702623
The remainder is 622 after subtracting 2058 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

The final outcome is 17580.13702623, with a leftover of 6.22e-07.
